Proxima Centauri, 4.3 light years away.
It is the dimmest of the 3 stars that make up the Alpha Centauri star system. From Earth, they appear as a single star. The other 2 brighter stars are Bungula (alpha Centauri) and Agena (beta Centauri), which revolve around each other, next to Proxima.
In the sky, you can find the constellation of Centauri between that of Scorpio and Sagittarius, at Latitude 42 degrees South.

Our Sun is the nearest star. It is about 8.32 light minutes away from Earth. The next nearest star is Proxima Centauri that is about 4.3 light years away. It has two companion stars that are a bit further away. The system is named for Alpha Centauri, the brightest of the three. The third star is called Beta Centauri or Alpha Centauri 2.

The nearest star to our solar system is Proxima Centauri, a tiny Red Dwarf star some 4.22 lightyears away from us, third member of the Alpha Centauri triple system.

The nearest star to our Solar System, and the second nearest star to Earth after the Sun, is Proxima Centauri. It is 39.9 trillion kilometres away. This is 4.2 light years away, meaning that light from Proxima Centauri takes 4.2 years to reach Earth.

Proxima Centauri has been suggested as a logical first destination for interstellar travel, although as a flare star it would not be particularly hospitable. The current standard spaceship, the Space Shuttle, travels in orbit at 7.8 km/s. At that speed, it would take 160,000 years to reach Proxima. The fastest man-made spacecraft, the Helios II deep space probe, has set a speed record of 70.2 km/s. Even at that speed, the journey to Proxima Centauri would take 18,000 years. The proposed VASIMR propulsion system, possibly able to achieve speeds up to 300 km/s, would shorten the journey to a "mere" 4,200 years —still firmly beyond the current lifespan of both man and machine. It follows that interstellar travel would require significant development of radical ideas to become feasible, such as hypothetical generation ships, laser-pushed solar sails, nuclear fusion powered Bussard ramjets, nuclear pulse drives or warp drives.

There is only one star in our solar system, and that is the sun, and it is 93 million miles away. The closest other star is Proxima Centauri, about 4 light-yrs away

nearest star in our solar system is the Sun. The other is Alpha Centauri, its about 4.39 light years away (25.8 trillion miles).

the closest start to the earth is the proxima centauri, 4.2 easy years away. it is a member of the great call team alpha centauri, including 3 stars. (not so useful with reference to the call of the great call team)
