We all know the Earth exerts gravity on us, but other objects in the solar system also pull on us. In the following series of problems we will investigate how strong gravity is for a person standing on the surface of the Earth from various objects in the solar system. You can answer the following series of questions using Newton's Law of Gravity; use the units given and the Gravitational Constant, G = 6.67 ×10-11 m3/kg/s2.

What is the force of gravity due to the Earth on a 46.0 kg ASTR 110 student standing on the equator during Spring Break. DATA: Equatorial radius of the Earth 6.378×10⁶ meters; mass of the Earth 5.98×10²⁴ kg.
What is the force of gravity due to the Moon on a 46.0 kg ASTR 110 student standing on the equator during Spring Break. DATA: mean distance to the Moon 3.84×10⁸ meters; mass of the Moon 7.36×10²² kg.
When Jupiter is on the same side of the Sun as the Earth the distance between the Earth and Jupiter can be as small as 6.30×10¹¹ m. Knowing this, what is the maximum force of gravity due to Jupiter on a 46.0 kg ASTR 110 student standing on the equator during Spring Break. DATA: Mass of Jupiter = 1.90×10²⁷ kg.
Some people claim that the location of Jupiter can have dramatic consequences on human events on Earth. For comparison to the last problem, what is the force of gravity due to a 100 kg person hugging a 46.0 kg ASTR 110 student. Assume the distance between the students is 0.3 meters.

5. Other Solar Systems. Suppose we found a solar system with the properties described (note that these are not real discoveries!). In light of our theory of solar system formation, decide whether the discovery should be considered reasonable or surprising. Explain your answers. A.

As the galaxy is moving and the solar system orbiting the galaxy and the Earth orbiting the sun. So how fast is each object moving and what is the fastest we move at? Do we even know how fast the galaxy is moving that is not relative to another galaxy (although I guess velocity has to be measured relative to something).

Observing the solar system model of concentric circles with center being the sun. The Earth is 1 AU from the sun. 1 AU is equal to about 150 million kilometers (93 million miles). Using a scale factor of 1010 meters per astronomical unit (AU); let say that the Earth is 15 meters away from the sun. And let say, Earth takes on an average 365 days to complete a full cycle around the sun. How far Earth travels in its...

The orbital region of Earth is known as the Goldilocks region in our solar system where the probability of life to exist is higher than any other regions which may be too hot or too cold. My question: Why did we make such a wild assumption that, for life to exist we need a neither hot nor cold region or there has to be oxygen and water? There might be alien life which require say Plutonium or Mercury to live....
