Using our telescopes, astronomers have confirmed the existence of a Super-Earth in the temperate zone of a nearby Sun-like star!
The star in question, known as HD 20794, is located just 20 light-years away. The planet is six times more massive than Earth, and it takes 647 days to complete an orbit around HD 20794 star, 40 days less than Mars around the Sun.
This feat was made possible thanks to over two decades of observations from the ESPRESSO and HARPS instruments, installed at our Very Large Telescope (VLT) and 3.6-metre telescope respectively, both in #Chile's Atacama Desert.

The orbits of the most internal planets are surrounded by a green shaded region labeled “Habitable Zone”, with the orbit of one planet passing through it. (remote)
