There is a rule about how things in the solar system move and you can use it to draw similar diagrams. All major motions in the solar system are in a COUNTER-CLOCK WISE direction when observed from above the North Pole. This includes the motions associated with the Earth, the Moon, the orbital motions of the planets, and most of their rotation motions as well. There are of course some exceptions, but they aren't that common. If you have to quickly draw any solar system motions, you'll know which way the stuff is moving - again, there are a few exceptions and I'll tell you what they are if necessary....
