Hubble Telescope Confirms Earth-Sized Exoplanet in Nearby Star System

LTT 1445Ac, a rocky world with similar gravity to Earth, orbits a red dwarf star 22 light-years away but has a surface temperature too high to support life.

Hubble Space Telescope has measured the size of the nearest Earth-sized exoplanet, LTT 1445Ac, revealing it to be a rocky world with roughly the same gravity as our own.
LTT 1445Ac orbits a red dwarf star in a triple system, 22 light-years away from Earth, in the constellation Eridanus.
The planet's surface temperature is estimated to be around 500 degrees Fahrenheit, making it unsuitable for life as we know it.
LTT 1445Ac was first discovered in 2022 by NASA’s Transiting Exoplanet Survey Satellite (TESS).
Further observations and studies of LTT 1445Ac's atmosphere are anticipated, which could provide insights into the formation and evolution of Earth-like planets.
