And Complete Solutions
What two properties of a planet affect the gravity we feel on its surface? - CORRECT ANSWER mass and
radius

Say that there were a planet X in our Solar System with a mass 1/4 the mass of Earth and a radius 1/2 the
radius of Earth. How will the gravity on its surface compare to the surface gravity of Earth? - CORRECT
ANSWER surface gravity on planet X is the same as on earth
A planet in a nearly circular orbit with its rotation axis tilted by 5 degrees relative to its orbital plane
around its star would: - CORRECT ANSWER have seasons that are not very different from each other as
compared to Earth's
The rotation axis of the Earth is: - CORRECT ANSWER tilted at about 23 degrees relative to the axis of the
Earth's orbit around the Sun.

in orbit around the Sun? - CORRECT ANSWER Summer on Uranus
