millions of years, but it varies with location is the galaxy.
for example in the milky way our solar system orbits once every 225 million years but stars further out orbit slower and those further in orbit faster.
It takes 24 earth hours for it to make a full rotation.
Venus, which rotates backwards in comparison to Earth, takes 243 days to make a full rotation on its axis.
24 hours
27.3 days.
venus completes an orbit every 224.65 days.
because that's how long it takes for Earth to make one full rotation.
4332.59 Days to orbit the sun
116.75 Earth days.
I think its about 67days. Not sure now sha
it takes mars 24.6 hours to rotate on its axis once
365 1/4 days
It takes Mercury 1407.6 Earth hours to make one full rotation around its axis.
