Simply because it is too dim to see with the naked eye. Proxima Centauri is a red dwarf; basically, red dwarves are much dimmer than our Sun.
Proxima Centauri is too dim to bee seen without a telescope.
To view things from far away is called a binocular
Probably white dwarfs and red dwarfs that are too dim to see, except for the nearby ones like Proxima Centauri, the closest star, but that needs a big telescope to see it.
Distance is one of three factors affecting the "apparent" magnitude of a star. The other two are "absolute magnitude", or how bright it REALLY is, and the amount of dust and gas between the other star and our solar system. For example, the closest star to Earth (other than our Sun, of course) is Proxima Centauri, 4.2 light years away. Proxima Centauri is NOT VISIBLE to the naked eye; it is a tiny red dwarf, so dim that you need a telescope to see it.
Alpha Centauri is a triple star system. Alpha Centauri A, B & C or Proxima Centauri. Alpha Centauri A & B are 4.37 light years from the Earth whereas Alpha Centauri C is 4.243 light years.

Not without a telescope. Proxima Centauri is a dim star.
Proxima Centauri is a red dwarf and the third star of the binary system of Alpha Centauri. You need to be 'below' -600 latitude and have have a telescope capapble of resolving a a star with an Absolute Magnitude of 15.5 or better. Which is a very powerful telescope for any but professional astronomers. It can only be seen from a very few places in the US, and then very poorly as it is too near to the horizon even at its highest.

When you look up at the sky at Proxima Centauri, you see it as it was 4.2 years ago. It will be another 4.2 years from now before somebody at Proxima Centauri sees you looking down at him. He will be troubled, and will wonder why you are looking down at him.

The closest star would be Alpha Centauri A (Not to be confused with Proximus Centauri) which has a stellar class [See Link] of G2V which is the same as our Sun. It's distance is about 4.3 light years away.
Proxima Centauri is the closest star to our Sun, at 4.2 LY. Curiously, even though it is the closest, it is not visible to the naked eye! Proxima Centauri is a tiny red dwarf star, and requires a fair-sized telescope to see. For a long time, many people thought that the closest star was Alpha Centauri, which isn't entirely incorrect. The Alpha Centauri system is actually a double star with a very distant triple; Alpha Centauri A (also known as Rigel Kent) and Alpha Centauri B form a binary system, and Proxima, Alpha Centauri C, is very distantly linked at about 0.3 LY.

The star nearest to the Earth is Sun, but except Sun, The closest star system that we know of is Alpha Centauri, located about 4.37 light years away (41.5 trillion km). The system easy to see with the unaided eye - if you live in the Southern hemisphere. In fact, Alpha Centauri is the 4th brightest star in the star in the sky. Alpha Centauri is actually made up of three stars orbiting one another. They're too bright to be seen as separate stars without a telescope. But with a telescope, it's possible to split the star into two. These are Alpha Centuari A and B. Neither of them is very closer to the Earth. The Alpha Centauri system has a third, much dimmer star called Proxima Centauri. While Alpha Centauri A and B are 4.37 light-years away, The red dwarf Proxima Centauri is located a mere 4.22 light-years away. Alpha Centauri orbit one another, getting as close as 11.2 astronomical units (the distance from the Sun to Saturn), while Proxima Centauri is about 13,000 astronomical units away. Most astronomers think that Proxima Centauri orbits the binary pair, but there are some who think it's just passing by, and not actually part of the system.
ANSWER:With the Sun being the first, Proxima Centauri is the next closest at 4.22 light years away in the Alpha Centauri star system. See the related link for more information.
