Uranus
 Just like Venus, Uranus rotates from east to west.
 It has 27 natural satellites.
 The rotation axis of Uranus is highly tilted.
 The atmosphere of Uranus comprises hydrogen and
methane gas mainly.

Neptune
 It is the farthest planet from the sun hence It takes the most
time to revolve around the sun.
 It has 14 natural satellites of its own.

Orbital and Equatorial Plane of the Earth
Orbital Plane of the Earth
We know that earth revolves around the Sun in an orbit. The plane in which it revolves
around the Sun is called its orbital plane.
Equatorial Plane of the Earth
The Equator is an imaginary line drawn from the middle of the earth. The plane of the
equator is called the equatorial plane.

Earth rotates on tilted axis
o
The equatorial plane and the orbital plane of the earth are inclined at an angle of 23.5 .
o
Hence, the axis of the earth is tilted at an angle of 66.5 to the orbital plane.
