D. Proxima Centauri

Answer:

D. Proxima Centauri is the nearest start to the Earth

The nearest star to Earth is Proxima Centauri. It is located in the Alpha Centauri star system, which is the closest star system to our Solar System. Proxima Centauri is approximately 4.24 light-years away from Earth, making it the closest known star to us.

Proxima Centauri is a red dwarf star, much smaller and cooler than our Sun. Despite its proximity, it is too faint to be seen with the naked eye from Earth. However, it plays a key role in studies related to exoplanets and the search for potential habitable worlds outside our Solar System.
