Why would an astronaut weigh more on the Sun than the Earth?

When you measure the distance between two bodies to find gravitational force, you should measure

Kepler's 2nd law is also known as

This law says that the Sun is always the focal point of an orbit. Empty space is the second focus, and planets orbit in an ellipse shape

This law says that in orbit planets sweep equal areas in equal amounts of time

This law says that a planet's T2/R3 ratio is always close to 1

A 35.0kg probe lands on a planet. The planet's mass is 7.34 x 10^22kg . The distance from the center of the probe to the center of the planet is 2.75 x 10^7m. Find gravitational force (G is 6.67 x 10^-11 n*m^2/kg^2)

If the orbital period (yr) is 0.24 and the Radius (AU) is 0.39, what is the planet's T^2/R^3 ratio?

Which of the following statements is correct?

An 80.0kg space probe lands on Mars. Mars has a mass of 6.42 x 10^23kg. If the distance to the center of Mars to the probe's center is 3.40 x 10^6m, what is the gravitational force? (G=6.67 x 10^-11)
