We tend to assume that planets orbit stars on more-or-less circular paths, but that’s not always the case – even Earth swings into a more oval orbit every now and then. But that’s got nothing on HR ...

How does a planet’s size influence its orbit around its parent star? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of ...

A planet unlike anything ever discovered before has been identified by a team of U.S.-led scientists. The planet, named HR 5183 b, is about three times the size of Jupiter—the biggest planet in our ...

NASA's astronomers have recently discovered a ‘quasi-moon' orbiting within Earth's orbital neighbourhood. This quasi-moon ...

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 ...

This artist’s impression shows a Jupiter-like exoplanet that is on its way to becoming a hot Jupiter — a large, Jupiter-like exoplanet that orbits very close to its star. NOIRLab/NSF/AURA/J. da Silva ...

The unprecedented discovery of a Jupiter-sized planet in orbit around a white dwarf star suggests it’s possible for planets to survive the tumultuous death throes of their parent stars. Imagine a dim, ...

Strange giant planets known as hot Jupiters, which orbit close to their suns, got kicked onto their peculiar paths by nearby planets and stars, a new study finds. After analyzing the orbits of dozens ...

The series "Imaginary Earths" speculates what the world might be like if one key aspect of life changed, be it related to the planet or with humanity itself. Earth is the only planet traveling within ...

Scientists have confirmed the existence of an "extraordinary" hot Jupiter-type planet that may help explain how the gas giants of our own solar system were formed. The planet, named Kepler-1704b, ...
