Jupiter-like planet 8 UMi b, named Halla, orbits its host red giant star Baekdu closely. The red giant's merger with a white ...

Astronomers have detected an exoplanet with a highly oblong orbit that experiences wild temperature swings — and it may be transitioning into another type of world. The exoplanet, named TIC 241249530 ...

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 ...

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 ...

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 found evidence of a previously-undetected dwarf planet at the edge of the solar system. The object, dubbed 2017 OF201, follows an extreme, oblong orbit, taking some 25,000 Earth years ...

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 ...

A newly discovered system of six planets circling a nearby Sun-like star may be the key to unlocking how planetary systems form. All between the size of Earth and Neptune, the worlds are orbiting in a ...

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 ...

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 ...

We worked out how many trips each of the solar system's eight planets has taken around the sun over the past 4.6 billion years. When you purchase through links on our site, we may earn an affiliate ...
