What is the closest star to Earth? 

Answer 1

The closest star to Earth is the Sun. The Sun is a star located at an average distance of 93 million miles (149.6 million kilometers) from Earth. It is the source of light and heat for our planet and is essential for life on Earth.

Answer 2

The closest star to Earth is Proxima Centauri, which is about 4.24 light years away from our planet. It is a red dwarf and part of the triple star system called Alpha Centauri, which is also one of the brightest stars in the sky. Proxima Centauri is too dim to be seen with the naked eye and was discovered in 1915 by Scottish astronomer Robert Innes. In recent years, scientists have been studying Proxima Centauri for signs of exoplanets that could support life, and in 2016, a potentially habitable planet orbiting the star was discovered.
