A step-by-step explanation for why planets that orbit a double star eventually enter an unstable orbit and disappear from the system. Of the more than 4,500 stars known to have planets, one puzzling ...

Forget what you learned in school. The solar system isn't just a flat disc of planets it's a 3D bubble moving through space. This video explains why all planets orbit in the same flat plane and what ...

Why is it so rare to find exoplanets orbiting two stars, also called circumbinary planets (CBPs)? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team ...

Pluto will complete its first orbit since 1930 in 2178, a historic 248-year space journey that spans generations of humans.
