Astronomers spot ‘overweight’ planet that appears too big for tiny host star

Discovery of planet too big for its sun throws off solar system formation models

The discovery of a planet that is far too massive for its sun is calling into question what was previously understood about the formation of planets and their solar systems.

Exoplanet 13 times bigger than Earth found orbiting star 9 times smaller than our Sun

Researchers have detected an exoplanet that appears to be far too massive for its host star. According to the study published in the journal Science, researchers said the exoplanet- called LHS 3154b- is 13 times bigger than Earth, and is orbiting the star called 3154, which is nine times smaller than the Sun.

Massive exoplanet orbiting small star upends planet formation theories

Astronomers have found a massive planet orbiting a small, cool star, and planet formation theories struggle to explain its existence.

Cosmic Mystery Stumps Astronomers: How Can Such a Huge Planet Orbit Such a Tiny Star?

The planet is 13 times larger than Earth and is circling a star nine times smaller than the Sun — a situation once believed to be impossible.

Newly discovered exoplanet should be too big to exist

The observation of an exoplanet has shaken up previous wisdom on planet formation because it is far too big for its host star.
