Random Planet Generator


This planet orbits a main sequence star of spectral class ??V —  meaning that it appears ? times as bright as the Sun, ? times as as large, and ? as massive.
On average, a star of that kind exists for about billion years. 
Your star's own age is % of that, or about million years.
An Earth-like planet could exist between A.U. and A.U. from the star (assuming no other stellar companions), with an ideal distance of A.U. 
A condition similiar to that of Venus would lie at A.U. from the star, while a condition similar to that of Mars would lie at A.U. away.
