The next closest known star to the Earth is Proxima Centauri, red dwarf star approximately 4.2 light years frâ¦om Earth ... only about 278,000 times as far from us as the Sun is. See the related link below for further information about Proxima Centauri.
Therefore, the distance between the earth and the sun varies throughout the year. At its nearest point on the ellipse that is the earth's orbit around the sun, the earth is 91,445,000 miles (147,166,462 km) from the sun. This point in the earth's orbit is known as perihelion and it occurs around January 3.The earth is farthest away from the sun around July 4 when it is 94,555,000 miles (152,171,522 km) from the sun. This point in the earth's orbit is called aphelion.herefore, the distance between the earth and the sun varies throughout the year.
