Why does the solar system have no gravity?

Answer 1

The planets and the Sun move around the center of mass of the Solar System. Because the Sun has much more mass than the planets, this center of mass is fairly close to the Sun.

Answer 2

The solar system does have gravity. Gravity is the force that holds the planets in orbit around the sun. The strength of gravity depends on the mass of the object - larger objects have stronger gravitational pull.

Answer 3

You can't. You can only see the Moon if light hits it.

Even if it is night where you live, the Moon still receives Sunlight. Only on rare occasions will the Moon be precisely in the Earth's shadow - but even then, it is not completely invisible, as it still receives some light, scattered in the Earth's atmosphere.

Answer 4

Yes. Gravity is caused by mass; the more mass, the more gravity. (We're entirely ignorant about the how and the why, but at least we know some of the "what" about gravity.)

Since the Sun has most of the mass, it also has most of the gravity, and the Sun's gravity keeps everything else from spinning off into the galaxy.

Answer 5

You can see the moon, even though it does not produce light, the same way you can see mountains in the daylight. The lunar surface reflects sunlight. When the moon is full, from our perspective, the earth is between it and the sun--so the entire lunar surface (that we can see) is in broad daylight. When the moon is new then the face of the moon is experiencing night.

Answer 6

The sun is the most massive thing in our solar system and takes up more than 99.9% of its mass and the more mass an object has the more gravity it has.

Also the planets are much bigger than comets and asteroids so the comets and asteroids would be the ones doing the orbiting :)

Answer 7

They don't orbit the earth, only the moon orbits the earth. But all planets orbit the sun because of the gravitational pull. The mass of the sun exceeds the mass of the earth a million fold, and is well over a thousand times the mass of all the planets in our solar system combined. Gravitational pull (force) is also why the moon orbits the earth.

Answer 8

Light is energy which is produced by stars, such as our sun.

When the sun converts hydrogen to helium in its core, significant amounts of energy is released as heat and light which is pushed through the solar system.

When the light hits the moon the light is reflected. If we view the moon from the earth, we see the reflected sunlight.

The moon is a "dead" astronomical body. It does not have energy produced in its core (it is essentially a cold collection of rocks). It does not produce energy in terms of light.

The earth has a hot core but because the outer shell of the earth consist of a rocky crust, no energy (light) is produced either. Any light from the earth (which you can see from space) is also reflected sunlight.

If Jupiter and Saturn have had enough mass they would have been able to produce nuclear fusion in their cores similar to our sun. However, since they are relatively small, they can not do that. Most planets are too small to produce enough energy as light. You need to get to the size of a brown dwarf star (basically a very large Jupiter or Saturn which both are mainly hydrogen and a small amount of helium, like our sun). A brown dwarf is extremely faint compared to most other types of sun, but they do produce their own light.

Answer 9

The moon doesn't actually shine or give off any light. It needs the sun because it reflects the sun's rays, and therefore looks like it is giving off light when really it's just reflecting it.

Answer 10

the light from the sun is reflected off the moon. that is what produces the half moon and the full moon

you should have learned this in fourth grade......The light from the sun bounces off of it and makes us see it....there ya go!
