3 New Planets in Deep Space
A group of scientists have recently discovered three new planets in deep space that are roughly the size of Earth circling within the system. TOI-2267 is a binary star system that is approximately 190 light-years away from Earth. New insights into how planets can form as well as remain stable in double-star systems have been provided by this discovery, which was detailed in the journal Astronomy & Astrophysics. Previously, it was believed that double-star systems were too unstable to support highly complex planetary formations.
