And, the answer for the the question is :
Explanation:
If you’re a fan of the TV show “Lost in Space,” you may recall that the planet Alpha Centauri served as a refuge for spacefarers. Besides the sun, no other star in the galaxy is any closer to Earth than the triple star system known as Alpha Centauri. The two brightest stars in the Alpha Centauri system, A and B, are 4.35 light-years away from Earth. It’s 4.25 light-years to Alpha Centauri C, or Proxima Centauri.
Alpha Centauri is the closest star system to Earth, located about 4.37 light-years away in the constellation Centaurus. The system is made up of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Alpha Centauri A and B are a binary star system, meaning that they orbit around a common center of mass, while Proxima Centauri is a smaller star that orbits around the other two.
The Alpha Centauri system is of great interest to astronomers and space enthusiasts because of its proximity to Earth and the possibility that it may contain habitable planets. In recent years, several exoplanets have been discovered in the vicinity of the system, including Proxima b, a potentially habitable planet orbiting around Proxima Centauri.
Alpha Centauri A and B are similar in size and composition to our own sun, and are both approximately 4.3 light-years away from Earth. The two stars orbit around a common center of mass, with a distance of about 23 astronomical units (AU) between them. This is roughly the same distance as the average distance between Uranus and the sun in our own solar system.
Proxima Centauri, on the other hand, is a smaller and cooler star, known as a red dwarf. It is located about 4.24 light-years away from Earth, making it the closest of the three stars in the Alpha Centauri system. Proxima Centauri is also known to be a flare star, which means that it emits powerful bursts of energy that can be harmful to any planets in its vicinity.
The Alpha Centauri system has been the subject of many scientific studies and space missions over the years. In 2016, the Breakthrough Initiatives foundation announced a plan to send a fleet of small spacecraft to the Alpha Centauri system, with the aim of studying the planets and searching for signs of extraterrestrial life.
