Discovering a second hot Jupiter precursor is helping astronomers to confirm the idea that high-mass gas giants transform into hot Jupiters as they migrate from eccentric to circular orbits, the ...

New evidence suggests that billions of years ago, a star may have passed very close to our solar system. As a result, ...

Those measurements confirmed that a Jupiter-sized planet was orbiting the star and that its orbit was highly eccentric, bringing the planet extremely close to the star before flinging it far out.

If Jupiter's orbit became more eccentric the team found that Earth's orbit would be pushed into becoming more eccentric too. This means at times Earth would be even closer to the sun than it ...

If Jupiter’s orbit became more eccentric, it could push Earth’s sub-freezing regions to warm, making those areas more habitable. A planet’s tilt, therefore, can have a major impact on its ...

Astronomers have used NASA's TESS telescope to discover a new 'warm Jupiter' exoplanet with a strange orbit.

Super-Jupiters in particular tend to have more eccentric orbits than smaller, more Jupiter-like gas giants do, which suggests they formed in more turbulent star systems, where near-misses and full ...

Astronomers now have three possible theories to explain how weird hot Jupiter exoplanets form ...
