Distance Between Planets Of The Solar System | KM & Current
The main reason for the planets to vary their distance is due to elliptical orbits. No planet in our Solar System orbits the sun in a perfect circle which means that the distance between planets is never the same. For this reason, to calculate the distance, we use the average to measure how far planets are from one another.

Exoplanets
Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years []
Proxima Centauri b
Proxima Centauri b (or Proxima b), [5] also referred to as Alpha Centauri Cb, is an exoplanet orbiting within the habitable zone of the red dwarf star Proxima Centauri, which is the closest star to the Sun and part of the larger triple star system Alpha Centauri is about 4.2 light-years (1.3 parsecs) from Earth in the constellation Centaurus, making it and Proxima d, along with the
