The difference between mass and weight is that mass is how much matter is in an object and weight is how much gravity is acting upon an object. This applies to the Solar System by you would weigh different on other planets but your mass would be the same.

In the model below it can be observed that during a lunar eclipse the moon falls behind the shadow of the Earth.
In the other model the moon blocks out the sun casting a shadow on the earth. Which can be observed fully in the umbra, and partially in the penumbra.

The objects in the Kuiper belt orbit the sun because it is the most massive object around them.There is no other object for trillions of miles so they are attracted to the sun, also these bodies are relatively small and they don't have a very strong gravitational pull themselves so they are attracted to the sun, as like the planets. They actually ORBIT the sun because of the inertia and the speed it has drives it around in a circular or elliptical orbit around the sun.

Newton's Universal Law of Gravitation is stating that all objects with mass have a gravitational pull even if it is small. Such as a person has a gravitational pull even if they have little mass and weight. Every planetary body has it's own gravitational pull which is why everything is attracted to each other.

Spring tides are when the high tide is at it's highest and the low tide is at it's highest. This happens when there is a full moon and a new moon because the sun and the moon's gravitational pull work together to create a buldge on the Earth.  Neap tides are when low tides are at their lowest and the high tides are also at their lowest. This happens during the first quarter and third quarter moons when this happens the sun and the moon work against each other creating very low tides

The reason why the northern hemisphere experiences summer, while the southern hemisphere experiences winter is because the sun is more direct on the northern hemisphere and less direct (more spread out) in the southern hemisphere. The seasons are less extreme near the equator region because the sun has the same affect on it all of the time because it's always near the center of Earth. On the other hand, places near the poles would experience more extreme seasons because they are near the top and the Earth's rotation moves the poles around a lot in relation to the sun.

High tides happen when the the moon's gravity is pulling Earths' surface water out to make two bulges. Low tides happen when the moon and sun pull Earth in opposite directions.

A planet is a spherical mass of gas, rocks, and ice. An asteroid is a non spherical mass of rock and ice, are smaller than planets and orbit the sun, like planets. Some objects in our solar system are spherical because because they have an atmosphere to block things that are moving towards them. Also because of the objects gravitational pull. Other objects however, do not have enough mass to keep a regular shape.

An eclipse is when in space, one astronomical body passes in front of another object temporarily obscuring it. A lunar eclipse occurs when the earth blocks the sun from view during a full moon. A solar eclipse occurs when the moon blocks the sun and casts a shadow over the earth. This happens during a new moon
