Closest Earth-like planet only 22 light years away, scientists discover

Scientists have discovered an Earth-sized exoplanet named LTT 1445 Ac, located 22 light-years away. Although the planet’s proximity to our Solar System makes it an excellent candidate for exploration, its scorching surface temperatures make it uninhabitable. However, the similarities between LTT 1445 Ac and Earth provide an opportunity for researchers to study planetary evolution. The discovery was made using data collected by the Transiting Exoplanet Survey Satellite (TESS), and measuring transit data and radial velocity data helps scientists understand the properties of exoplanets, such as their radius, mass, density, composition, and structure.
