Prepare for Mars!

Mars’s rotation period is about 24 hours 40 minutes.

This means that if you observe at the same time each day, the surface moves around 10 degrees (backwards). So to see a complete rotation, it takes around 36 days.

If you observe continuously the surface moves around 15 degrees per hour forwards.

Telescopically, the most prominent feature on Mars is Syrtis Major. In previous apparitions, timing and the weather contrived to prevent me seeing it.

At about 01:30AM NOW, it is almost facing us!

Get out there!
