This is actually a trick question. The closest star to the Earth would be the Sun, at a distance of about 93 million miles. The closest star outside our solar system would be Proxima Centauri at about 4 light-years from Earth.

janette l gubala Answer: Our Sun is the closest star at 93 million miles distance. (That’s about 8 “light minutes”) Next is _alpha_ Centauri at a distance of 1.31 parsecs = 4.27 light years. A light year is 5.88 trillion (10^12) miles.

The closet star is the sun. The average distance between the Sun and the Earth is about 149 million kilometers or 93 million miles. Light from the Sun takes about 8.32 minutes on average to reach Earth, so that means that the Sun is 8.20 light-minutes from Earth. The Earth is 1 A.U. (Astronomical Unit) from the Sun, defined as 92.8 million miles or 149.6 million kilometers. The minimum distance (perihelion) is 146 million km (91 million miles) The maximum distance (aphelion) is 152 million km (94.
