  • Introduction to Video Content
  • The solar system is a strange place, especially when we consider that most stars have at least one partner, unlike our solo Sun. But what if we had multiple Suns in our sky? In this SciShow List Show, we dive into the fascinating world of multi-star systems and the planets that exist within them.When it comes to multi-star systems, there are different configurations. In a two-star system, a planet like Earth orbits around a single point, where two stars orbit each other. This is known as a binary system. Picture two best friends holding hands and twirling in a field of daisies, except their arms can stretch, making their distance apart variable. Planets can then orbit around this binary system in what's called a circumbinary orbit.One example of a circumbinary system is the Bebop 1 system, which has two gas giant planets. Astronomers have made two separate discoveries using three different telescopes to confirm that these planets orbit two stars in roughly circular orbits.However, things start to get even more complex when we consider systems with three or more stars. In these systems, the orbits can become quite complicated, especially for smaller planets that are more influenced by the movement of their stars. Yet, there are real examples of planets in these multi-star systems, like the Kepler-16 system, which has a Saturn-sized planet orbiting two stars.So how do we even know about these multi-star systems? Astronomers use various methods, including the transit method, where they observe a star's brightness dip as a planet passes in front of it. In a multi-star system, these dips can be irregular and more challenging to detect, but advancements in technology have made it possible to identify such systems.In conclusion, our solar system may seem strange, but compared to some of the multi-star systems out there, it's relatively straightforward. These systems challenge our understanding of planetary formation and offer a glimpse into the diversity of the universe. By studying these systems, we can gain valuable insights into the complex dynamics of star systems and the potential for habitable worlds within them.

  • It might not seem like it, but our solar system is… weird.
  • For one thing, unlike our solo Sun, most stars out there have at least one partner.
  • Imagine what the sky would look like if we threw another Sun into the mix.
  • What the orbits of all the planets would have to be to make it all work out.
  • Now, imagine if Earth had three Suns, or four.
  • Some planetary systems actually work like that.
  • And to make it happen, the orbits can get a little brain-bendy, especially for any planets, which, being a lot less massive, are a lot more beholden to their star's movement.
  • So in this SciShow List Show, we're exploring some of those wacky multi-star systems, how planets can exist inside of them, and how we even know about them in the first place.
  • Now, organizationally speaking, our one-star system is not too far off from some two-star systems.
  • In that setup, a planet like Earth still orbits around a single point.
  • Only now, that point isn't where one star exists, but rather where two stars orbit each other.
  • Those two stars form what's known as a binary.
  • And they're just swinging around each other like two besties, holding hands and spinning in circles in a field of daisies.
  • If those besties also had really stretchy arms so they weren't always the same distance apart.
  • Now, a planet can circle around that binary in what's called a circumbinary orbit.
  • That's how the Bebop 1 system works.
  • Thanks to two separate discoveries using three separate telescopes, astronomers know that Bebop 1 has two gas giant planets that both orbit two stars in roughly circular orbits.
  • That's a lot of bodies swinging around each other, but gravity allows it because proportionally, the stars are much closer to each other than either of them is to a planet.
  • While the stars orbit each other once every 14.6 days, the inner planet orbits the binary once every 95.2 days.
  • So if you were in a levitating city on one of those gassy planets, it would look like Star Wars' Tatooine.
  • There would be two suns in your sky that stay relatively close to each other.
  • Now, aside from adding credibility to Star Wars' stunning sunsets, Bebop 1 is an exciting system for researchers because it's bright enough to be a new target for the Webb telescope.
  • It could teach us about the atmospheres of circumbinary planets and, as the researchers say, provide a new hope to unravel their mysteries.
  • So that's an example of a two-star system.
  • And adding just one more star, going from a binary to a trinary, can't change too much, right?
  • Well, it turns out that that third star makes things so much more complicated.
  • Now, one of them could get kicked out, or the entire system could fall apart.
  • And that's not even getting to the planet issue.
  • Sure, maybe physics would allow a trinary version of the Bebop 1 system, with a planet or two orbiting super far away from the complicated dance three stars have to do with one another.
  • But there are cooler arrangements that exist, too.
  • For example, instead of orbiting all three stars at once, it's mathematically possible for a planet to orbit just one of the stars, which is then in its own long-distance relationship with a binary.
  • And guess what?
  • The trinary next door actually has this arrangement.
  • Collectively, the three stars that make up the Alpha Centauri system are about 40 trillion kilometers from our Sun.
  • Which is simultaneously super far away, and still three times closer than any other sun-like star out there.
  • The two central stars, known as Alpha Centauri A and Alpha Centauri B, are very similar to ours in terms of appearance.
  • But the planets we've found are orbiting the third star in that trinary, a red dwarf called Proxima Centauri, which is only about 14% the size of our Sun, and 0.15% as luminous.
  • So it's a little guy, but it's got enough going for it to have at least two planets — one a little more massive than Earth, and the other one that's closer in mass to Mars.
  • If you were standing on either of these planets, a daytime sky would be a little more red and a little less bright than you're used to.
  • Because even though you're in the orbit of such a dim star, you're way closer than the Earth is to the Sun.
  • And unfortunately, Alpha Centauri A and B are so far away, they'd just be two distant white dots among a sea of stars.
  • Which is a bit disappointing from a space tourist's perspective, but sometimes you've gotta make sacrifices to fit three whole stars into one planetary system.
  • Now, there are plenty of binary and trinary systems out there, but systems with four stars are harder to find.
  • So you might think that only the most experienced researchers with dozens of publications under their belt could identify a planet in one.
  • But the first four-star planetary system was discovered by a group of amateurs.
  • Now, before 2012, researchers knew that there was a stellar binary in the system with the melodious catalog name KIC 4862625.
  • But that system was about to get totally reclassified thanks to citizen scientists, who may not have had any background in physics or space science.
  • They were volunteers who spent their free time looking through data collected by NASA's Kepler and TESS missions, just because it's cool.
  • It's a project called Planet Hunters, where anyone can sign up to comb through this public data in hopes of finding new exoplanets.
  • And in this case, those hopes turned into results.
  • Each volunteer is randomly assigned a small section of the mission's datasets from over 300,000 stars, and their job is to draw a box wherever they see evidence of a little dip in a star's brightness.
  • Because sometimes what they're seeing in that dip is a planet passing in front of its star, blocking some of the light from reaching us.
  • And sure, you could do some of this work with a computer program.
  • But if there's more than one star in close proximity, like when there's a binary, the planet's signal can be hidden among the dips caused by the two stars blocking some of each other's light.
  • And where algorithms might fail to spot that detail, human eyes can catch something worth following up on.
  • Spoiler alert, that's what citizen science did for KIC 48… all those numbers.
  • But once this particular system caught their eyes, these amateur astronomers looked deeper and found a second binary of stars that had been there all along.
  • This was a four-star system, making it the first four-star system with a planet in it, as far as NASA knows.
  • So there's a binary of stars circling each other, with a planet orbiting both of them, and another stellar binary going around all of that.
  • If you were looking at the sky from this quadruple-star planet, you'd probably see two suns and one very bright star, which is actually two stars smooshed right up together.
  • It's like how from Earth, you can look up at the Big Dipper and totally miss that some of the stars are actually multi-star systems.
  • So hats off to citizen scientists for showing us cool systems like this one.
  • And yes, astrophysicists then officially confirmed the findings.
  • But this huge discovery could have been made by you, or your neighbor, or the person operating the camera for this SciShow video.
  • And since that discovery, researchers have started to realize that four-star systems are more common than they used to think.
  • But a planet in a five-or-more-star system?
  • That's still hypothetical, at least of this filming.
  • Astronomers have found systems with five, six, and maybe even seven stars, and odds are there are more out there.
  • So we know that stars can group together in these big batches.
  • But at this point in time, we haven't found any evidence that a planet can coexist with all of that.
  • I mean, it's hard enough to find all of the stars in a crowded system.
  • For example, in the five-star system, whose name I'm not even going to try to say out loud, researchers were totally missing the fifth star for over a year.
  • They originally reported two binaries in a double-eclipsing four-star system.
  • The dimmer binary was identified first, because they thought the brighter one was just a twinkle glinting off one of the other stars.
  • But something about this system made them want to look deeper.
  • Even after they thought they'd determined that it was a four-star system, they kept an eye on it because the two stars in one of the binary pairs orbited each other faster than in any known four-star system.
  • So when another research team claimed to find a fifth star traveling at the same velocity as the rest of them, the original team agreed that it's probably a package deal.
  • Maybe one day astronomers will find out there's a planet in that package, too.
  • Or maybe they won't.
  • But while we're shooting for the stars, why not talk about six-star systems that could theoretically be home to planets, too?
  • One six-star system we've recently discovered is called TYC 7037891.
  • It's made up of three binaries that are all similar in mass, size, and temperature.
  • Two binaries orbit each other, then those four do a big dance with the third binary.
  • Now, each of the binaries has a pretty short orbital period of only a matter of days.
  • They're all tight pairs.
  • But the orbits of the binaries around each other are much larger, giving them room to spin around each other as they move.
  • They're also far enough away that each binary can act like just one source of gravity, making the physics a lot less messy.
  • Ultimately, there might be other kinds of six-star systems out there, like two sets of triplets.
  • But because the third star in each triple would have to orbit so much farther away, we're more likely to find six-star systems like TYC, a triplet of binaries.
  • Since these larger, more complicated systems are harder to find and stick together in the first place, it might not be too surprising that we haven't found any planets in them so far.
  • But in space, sometimes you just have to keep looking.
  • Maybe a few years of searching will lead to new discoveries.
  • And we're going to make them all from our solar system with just the one star, which works perfectly well for us.
  • One thing that all of these solar systems have in common is that their stars are brilliant, just like this video's sponsor.
