Only 1.5 Light Years away, habitable planet REJIS 783k was discovered in 2019,  half the volume of Earth, REJIS783K straddles the line between "Super-Venus" and "Mini-Earth" and scientists are sure that it has a rocky surface with vegetation similar to that of Earth. One thing is certain though: at five-sixth times the Earth's mass, its gravitational pull is slightly weaker than that of Earth. Scientists have found out that there is an ocean of lava in this planet. This ocean of lava is categorized into two types based on the surface temperature. The  temperatures in the night side is lower than that of the day side , but what makes it boiling hot at the cold temperatures(in Oort cloud) is still a mystery.
