Astronomers Find Inner Solar System with Intriguing Similarities to Ours and Located “Next Door”

Astronomers had always been trying to find a new home for all of us out there in the vastness of the Cosmos. Exoplanets don’t represent anything new anymore for a few decades. Judging only by how huge our Milky Way galaxy is, there should be many habitable worlds out there lurking in the dark.

Until astronomers ever find a “new Earth”, first they have to observe the star it revolves around. EarthSky reveals that on August 5, 2021, astronomers claim that they’ve found a planetary system that is incredibly similar to our own after they had been using the European Southern Observatory’s Very Large Telescope. One of the planets is suspected of having oceans. There are at least four rocky planets, possibly even a fifth one. Sounds familiar, right? Our Solar System also has four: Mercury, Venus, Earth, and Mars.

Last but not least, the entire system is located practically “next-door”, judging at an astronomical scale.

L 98-59 is only 35 light-years away

L 98-59 is the host star of the newfound planetary system, and it’s practically located next door to us. At 35 light-years away, it means very close.

All of the known planets from the nearby planetary system are classified as super-Earths, as they’re rocky objects larger than Earth but smaller than Neptune.

The planet known as L 98-59d is also very exciting. About 30% of its mass is likely represented by water. This means that the planet is an ocean world. However, scientists aren’t sure that the planet’s water is located below or above the surface if it really exists. The planet also has a mass 2.31 times the one of Earth, and it orbits its host star in only 7.5 days.

The researchers detailed the new findings in the peer-reviewed journal Astronomy & Astrophysics.
