A rare planet has been discovered hundreds of light years away, and it could prove key to our understanding of planetary formations out there in the universe.

There have been more than 5,300 exoplanets discovered, but few match the description of the newly recorded TOI-733b.

Found 245 light-years away, TOI-733b is almost twice the size of Earth and orbits a sun slightly smaller than our Sun.

While there are many exoplanets, there is a surprisingly small number that sit between one and a half and two times the radius of the Earth, and it’s the size that makes it so interesting to scientists.
