New rocky planets with Earth-like climates found

(ORDO NEWS) — An international team of astronomers, led by scientists from the University of Birmingham, has announced the discovery of two new rocky planets with Earth-like temperate climates.

The findings of the observations are published in Astronomy & Astrophysics.

The found objects revolve around LP 890-9, a small cold star located about 100 light years from Earth.

The system’s inner planet, called LP 890-9b, is about 30 percent larger than Earth and orbits its parent star in just 2.7 Earth days.

It was initially spotted by NASA’s Transiting Exoplanet Survey Satellite (TESS) as a planet candidate and later confirmed by the SPECULOOS telescopes.

This is what made it possible to find also the second planet LP 890-9c. It is similar in size to the first (about 40 percent larger than Earth), but has an orbital period of about 8.5 days.

In the future, experts want to explore its atmosphere using the James Webb telescope.

In August 2022, astronomers were able to prove the presence of carbon dioxide in the atmosphere of an exoplanet for the first time thanks to the Webb Space Telescope (JWST).
