These six planets are in perfect sync with each other as they dance through space around their star. Credit: Roger Thibaut (NCCR PlanetS) Astronomers have observed a solar system where six planets are ...

An illustration of the solar system and the planet's orbits around the sun When you're standing on Earth's surface, it's easy to forget that our planet is hurtling around the sun at more than 67,000 ...

One hundred light years away, a handful of planets are circling a star in the same configuration as when they formed. By Katrina Miller Astronomers have discovered six planets orbiting a bright star ...

Scientists have discovered a rare sight in a nearby star system: Six planets orbiting their central star in a rhythmic beat. The planets move in an orbital waltz that repeats itself so precisely it ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close binary system—an arrangement previously thought impossible. Using advanced ...

Planet hunters have grown used to strange worlds, but a handful of discoveries now point to something even more radical: giant planets that loop around their stars on orbits so skewed they almost defy ...

For the inner four planets in this solar system, each planet orbits the sun three times for every two orbits of the planet immediately to its outside. For the fourth, fifth and sixth planets, they ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white dwarf star questions how Halla could exist. Credit: Space.com | animation ...

Luke found life on Tatooine to be boring, but he should be glad, because as we have seen, binary stars have the potential to play all kinds of havoc on their orbiting circumbinary planets. When you ...
