1. Proxima Centauri is a red dwarf star located 4.2 light-years from Earth in the constellation Centaurus. It is the nearest star to our solar system, and it is a member of the triple star system called Alpha Centauri. One interesting fact about Proxima Centauri is that it is a flare star, meaning it is prone to sudden, dramatic increases in brightness. These flares are caused by the star's intense magnetic activity and can release as much energy as the Sun does over an entire day in just a few seconds. Proxima Centauri is also a low-mass star, with about an eighth of the mass of the Sun. As a result, it is relatively cool and red in color, and it has a much longer lifespan than more massive stars. It is estimated to be over 4 billion years old and is expected to last for another 4 trillion years or more. 2. How long would it take to get to Proxima Centauri? Obviously, if we travelled at the speed of light, it would take around 4.2 years. However this kind of speed is currently ...
