What is true about the area between points A, B and the Sun, and the area between points H, I and the Sun?

• The area between A, B and the Sun is the largest.
• The area between H, I and the Sun is the largest
• Both areas are equal in size
• There is not enough information to determine the areas

Kepler's 2nd Law deals with 

• the shape of the planets' orbits
• the speed/area the planet travels 
• the length of time it takes the planet to orbit the sun

Kepler’s 2nd Law states that the area swept out by a planet’s motion will be the same regardless of where it is in its orbit. A comet moves much faster when it is closer to the Sun than when it is further out from the Sun. What is the primary cause in the change of the comet’s orbital velocity?

• Jupiter's gravitational field.

• The sun's solar wind.

• The sun's gravitational field.

• Saturn's magnetic field.
