{'second nearest star': [1, 0, 0, 0], 'alpha centauri': [0, 1, 0, 0], 'proxima centauri': [0, 0, 0, 1], 'sirius': [1, 1, 0, 1], 'earth': [0, 1, 1, 1], 'vega': [1, 0, 0, 0]}

The correct answer is option 3, Proxima Centauri. Proxima Centauri is the closest star to our solar system after the Sun. It is located in the Alpha Centauri star system, which is approximately 4.24 light-years away from Earth. Vega and Sirius, options 1 and 2 respectively, are much farther away from us than Proxima Centauri. Alpha Centauri, option 4, is a star system that consists of three stars - Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the smallest and faintest of the three stars and is considered the closest neighbor to our solar system.
