Read the text and answer the questions choosing the right answer.

Alpha Centauri is a triple-star system. One of the three stars in Alpha
Centauri is Proxima Centauri, which is the nearest star to the Earth, except, of
course, for the Sun. The name “Proxima” comes from a Latin word which
means “close”.
Even though Proxima Centauri is the closest star to the Earth outside of our
solar system, it is not really close. Interstellar distances are so large that
they are almost impossible to imagine. A person traveling in a modern
spacecraft would not arrive at Proxima Centauri within this lifetime, or the
next, or even ten lifetimes because the distance is so great. Light travels at a
speed of 186000 miles per second, and it still takes light more than four
years to travel from Proxima Centauri to the Earth.
Alpha Centauri can be easily seen in the night sky without a telescope
from certain parts of the Earth. It is the third brightest star in the sky, out of
approximately 6000 visible stars. It cannot be seen from most parts of the
United States because most of the United States is too far north; however, it
can be seen from the southern parts of the southernmost states.
