【實用教育app】Planet Calendar|最夯免費app

A calendar indicates the position of the Earth in it's orbit around the Sun.

One complete orbit is one Earth year.

We can also see and track the positions of the other planets, and see how long it takes them to make one orbit, one year.

Accurately see where the planets are right now. Speed up the solar system to see where the planets will be in the future, or go back to see how the planets were aligned on specific dates, like your birthday.

Cycle through the planets to get their current year and see the solar system from a different point of view.
