The Solar System

the sun's gravity

An Orrery.

In our solar system there is one Sun and eight planets. Formerly Pluto held a slot as the ninth planet - but in 2006 the IAU decided to reclassify it as something other than a true planet, thus reducing the count to eight.

because of GRAVITY

Yes we believe most single star solar systems will have a simiar structure to ours.

Where the star has a binary companion (or more companions) it is more difficult to precict that an oort cloud would be stable over time....we dont know.

Gravity causes objects, like planets, to orbit the Sun.

The planets known as gas giants do include Jupiter and Uranus, as well as Saturn and Neptune.

It would ruin your whole day. Celestial mechanics makes this a non-existant threat, though, so you are relatively save. The collision of the two planets would destroy all life on earth and create a much larger planet, since the speed of collision would probably not allow for much to reach escape velocity.

No, the planets after Pluto are still within our solar system. After Pluto, there is Eris, Haumea, Makemake, and several other dwarf planets and minor planets that are part of our solar system. Beyond these, there is the Kuiper Belt and the Oort Cloud which are also part of our solar system.

They are both visible and inside the solar system.

Fragments or a sentence

They are Jupiter, Saturn, Uranus and Neptune.

A nebula, a large cloud of hydrogen gas, comes together under its gravity over a long period of time. One trigger may be perturbation from nearby supernovas.

Olympus Mons is located on Mars; at about three times the height of Mount Everest it is considered the second tallest mountain in the Solar System. The central peak of crater Rheasilvia on Vesta is slightly taller.

The gravity from a specific object (for example, the Sun) will become weaker if you go farther away from that object. The law of gravitation in general, and the gravitational constant, seems to be the same everywhere in the Universe.

For the same reason you wouldn't use a ruler to measure a paramecium. A lightyear is the distance that light travels in a year, about 6,000,000,000,000 miles. The reason it isn't used inside of our solar system is, simply, because the solar system isn't that big.

Earth days are normally rounded to about 24 hours, but in fact the time it takes for Earth to complete a full rotation (i.e. a day) is 23 hours, 56 minutes and 4 seconds. A year is approximately 365.24 days.

It's a planet if you mean the name- God of War

Our galaxy has over 200 billion stars; many of them do have planets, and thus qualify as a "solar system".

As to the total number, we will never know, as solar systems will live and die.

As a rough guess, at least 50% of all stars should have planets - so that could be classified as a "Solar System".

Greenhouse effect. The same effect that keeps Earth warmer than if there would be no atmosphere: without an atmosphere, the average temperature on Earth would be below zero Celsius.

No, the distance between the sun and the earth varies continuously because the earth's orbit is elliptical not circular. Also the position of the sun changes in response to the gravitational pull of the planets orbiting it (especially massive Jupiter).

It will be extremely hard and out of our technology but yes we can.

We need and object that will interact with the sun like a magnet that has a negative charge but push the sun at a very fast rate and bring a different star in the solar system.

Because (as far as we currently know) Earth is the only planet in our solar system that supports life.
