HOW FAR IS THE CLOSEST STAR?

HOW FAR IS THE CLOSEST STAR? At some point in our lives, we were all posing this question: How far and how long would it take to fly to the stars? Could it be within the timeframe of a human, and could this kind of travel someday become the norm? There are several potential answers to this issue, some in the world of science fiction, some are very simple. Yet coming up with a thorough response involves taking into account a number of things. Space is very big, like it or not, and our technology is still very limited. But we will have a number of choices to get to the closest solar systems in our galaxy.

Let’s start by answering first this question: What is the closest star on our planet? The simplest answer is the Sun, it is the nearest star to the Earth nearly 93 million miles away. . But maybe that doesn’t answer your question. Instead, the closest star of our system outside of our Sun is Alpha Centauri. This is not a single star, it is actually a triple-star system, three gravity-bound stars together. Two bright, closely orbiting stars with a distant which is the Alpha Centauri A and B, a dim companion called Proxima Centauri the closest start in the Earth. As already mentioned, Proxima Centauri is the nearest and closest start in our planet, which is why it makes the most sense to first plot an interstellar mission to this system. Proxima Centauri is now 40,208,000,000,000 km away, the nearest star to our planet. When we speak around distances from the stars; the light-year is usually used. The distance light travels in one year is a light year-it is equivalent to 9.461 x 1012 km. Our planet is approximately 4.35 light-years away from Alpha Centauri A and B, and 4.24 light-years from Proxima Centauri which is significantly closer to our own. In fact, Alpha Centauri, is the brightest star of the three in the system, while Proxima Centauri, the dimmest of the three, is an isolated red dwarf.
