It does NOT orbit on its axis, but rotates on its axis. It takes 24 hours, one day, to make one complete rotation. However, It does ORBIT the Sun. It takes the Earth 365.25 days, one year, for make one complete orbit of the Sun. Whilst it is making this orbit it is also rotating on its axis, as above.
Rather simplified: one orbit of the Earth round the Sun is a year. One rotation of the Earth on its axis is a day and a night of 24 hours.
There are three different "Earth days". I will point you to a couple of links that have information about "Earth days", and lunar orbit information. Roughly, the Moon completes one orbit in 28 days, so it completes 1/28th of its orbit.
One year.
It takes Earth approximately 365.25 days to orbit the Sun once. This period is known as a year.
Uranus takes about 30,687 Earth days (just over 84 Earth years) to make one orbit of the Sun.
It takes one year for the earth to orbit around the sun
it takes 365 days for the earth to make one complete orbit around the sun
The earth doesn't orbit the earth, but in a weird sense the answer would be one day (or better: 23 hours and 56 minutes.) To orbit the sun, one year. Or 365 and a quarter days.
Earth takes a lot longer to make one complete order around the sun than Mercury does. The time required for Mercury to make one orbit is equal to 88 Earth days (whereas one orbit for Earth is about 365 Earth days).
The Earth's spin, or rotation on its axis gives us a day.
