Astronomers have found more than 4,000 exoplanets, worlds orbiting distant stars in our Milky Way galaxy. Many reside in planetary systems vastly different from ours. But, on August 5, 2021, astronomers said they’ve found a distant planetary system that has intriguing similarities to our sun’s inner solar system. One of the planets is about half the mass of Venus, the planet next-door to Earth. Another could have oceans. And there might be yet another rocky world in this system’s habitable zone.
These astronomers used the European Southern Observatory’s Very Large Telescope to make their observations. The researchers published a new paper detailing their discoveries in the peer-reviewed journal Astronomy & Astrophysics on August 3.
It has 4 or 5 rocky planets
The host star, L 98-59, is only 35 light-years away. It has at least four confirmed rocky planets and possibly a fifth. That’s similar to our solar system’s rocky worlds (Mercury, Venus, Earth, Mars). But, in the L 98-59 system, the distance scales are different. And, by the way, all the known planets of L 98-59 are categorized as super-Earths. That means they’re rocky worlds larger in size than Earth, but ...
