"There really is something very different about how these giant planets form versus how small planets like Earth form." ...

The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some planets outside our solar system, ...

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 | Space ...

Planets change orbit shape around Neptune’s size. Metal-rich stars help giant planets form. Eccentric orbits suggest chaotic planet formation.

Its unusual elliptical orbit could impact its potential for life, making it a fascinating subject for future research. Three decades after the first exoplanet was identified, scientists have detected ...

As it orbits its star, it moves close enough at one point to experience extreme heat, similar to Venus’s temperature. But at its farthest point, the planet is nearly twice the distance from Earth to ...

With an orbit of 647 days, HD 20794 d is similar to Mars in our solar system. However, its orbit around the star is highly ...

An international team led by researchers in Japan and Europe has discovered a new multi-planet system around a Sun-like star, ...
