Hubble Telescope Identifies Earth-Sized Exoplanet with Similar Gravity
TL;DR Summary
The Hubble Space Telescope has accurately determined the size of an Earth-sized exoplanet named LTT 1445Ac, which orbits a red dwarf star in a triple system 22 light-years away from Earth. The observations revealed that the planet has a diameter 1.07 times that of Earth, making it a rocky world with similar gravity. However, its surface temperature of 500°F (260°C) makes it unsuitable for life. The findings highlight the importance of space telescopes like Hubble and the upcoming James Webb Space Telescope in the search for habitable worlds beyond our solar system.
