Gravity in Space & Scale Distance and Sizes

Which of these choices explains why this model of the solar system cannot be correct?

• Earth does not have enough gravitational pull to be located in the center of the Solar System.

• Venus is larger than the Moon so it would be located closer to the center.

• Saturn has as much mass as Earth so it would be located in the center.

• Mars and Mercury have an equal amount of gravitational pull so should be on the same orbital pathway.

What is a light year?

• It is the LUMINOSITY of the Sun compared to other stars.

• Like a regular year, only with less calories.

• It is the DISTANCE light travels in one year.

• It is the TIME it takes light from the Sun to get to the Earth.
