The second focal point of a planet's elliptical orbit is a mathematically determined point in empty space.

• True

• False

Kepler's first law is

• planets travel in an ellipse e=f/d

• planets sweep out equal areas in equal times A1=A2

• the farther the distance from the sun the longer it takes to orbit p^2=a^3
