When you look at the solar system, you might notice that the planets' orbits are tilted, and oddities in the protoplanetary ...

Researchers are studying eccentric warm Jupiters, giant exoplanets that follow odd, elongated orbits unlike anything in our solar system.

A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and Earth. The authors dubbed it Planet Y.

“The object’s aphelion—the farthest point on the orbit from the sun—is more than 1,600 times that of Earth’s orbit,” Institute for Advanced Study’s Sihao Cheng mentioned in a recent press release. As ...

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit ...

This artist’s illustration provided by the European Southern Observatory shows an exoplanet orbiting around two brown dwarfs, celestial objects that are lighter than stars, but heavier than gas giant ...

"It is possible that a planet once existed in the solar system but was later ejected, causing the unusual orbits we see today." Astronomers have discovered a massive new solar system body located ...

Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using a technique known as ‘transit timing variation’. In research ...

The Solar System has just gotten a new official member. Currently, with the name of 2017 OF, this is a trans-Neptunian object (TNO). This means that it orbits the Sun further away than Neptune.

A new Tatooine-like planet outside the solar system may orbit two failed stars, scientists reported Wednesday. Located about 120 light years away, the exoplanet appears to take an unusual path around ...
