What are the systems that affect earth's position and features.

Earth's position and features are affected largely by the sun, moon and other planets. Earth’s position in relation to sun forms climate changes, environment etc. Earth’s rotation is due to the pull from the sun as well as the moon, this rotation creates seasons, months, daylight and other related issues. Some planet’s gravitational pull like Jupiter and Saturn causes the tilt in Earth forming climate changes.
