The Solar System

That is commonly called a gas giant.

It is not any distance from it. Our solar system is in the Milky Way.

Galileo Galilei

Well there are a few ways:

1. Using telescopes and other sensory devices from Earth, or Near Earth Orbit.

2. Sending robotic probes around the solar system to gather information.

3. Physically sending humans in a spacecraft.

Of these, the third is the most expensive, which is why it hasn't been attempted beyond the moon. The other two are comparitively far cheaper and are readily used today to gather information about out solar system.

Most of these are a result of giant impacts

There is only one Solar Sytem; ours. Others are referred to generally as planetary systems. However, the Solar System was created roughly 4.6 billion years ago, gradually accumulating into a distinct system.

People in the solar system live on Earth.

Neptune is the farthest planet away from the Sun. It is cold, but actually warmer than Uranus.

If you visit the NASA website or even search for the "Milky Way", you can get a list of planets in our solar system. There are only 9 planets, 8 if you don't count dwarf planet Pluto.

While not absolutely accepted by all prior to Galileo, it was believed that the known Solar System, consisting of the visible planets, the Earth, sun and moon, was a geocentric arrangement. The five planets out as far as Saturn were known and studied for centuries. It was believed that these, the sun, the moon - and all the stars - moved in perfect concentric circles centred around the Earth. This was in line with ancient belief and adopted religious doctrine that placed the Earth at the centre of creation. When Galileo turned his small telescope towards the sky - a novel idea since its practical uses were deemed to be for use at sea - he observed that Jupiter actually appeared to have four small satellites that did not follow accepted doctrine. These, he observed over time, actually revolved around Jupiter itself. This contradicted the accepted belief that Earth was the central focus of the Universe. Announcing his discoveries and proclaiming his belief in a Heliocentric - or Sun centred - Solar System brought him into direct conflict with the Church. Under the threat of torture he was forced to publicly refute his claims. This did not stop his continued private beliefs in his work and it served as support for the growing evidence in the following years that confirmed this view.

Though there is evidence of other star systems (about 50), there is no evidence that any of these have planets that are able to sustain life. Additionally, no technology exists that enables travel to another solar system if a suitable one is found.

There's no need to "try". We've been radiating radio and TV out into the galaxy at

thousands of different frequencies for a little over a hundred years now, announcing

to anybody that's listening that we are here.

It's estimated that there are roughly 500 G-type stars ... the same type as our sun,

and the type thought to have the best chance of life somewhere in its planetary

system ... within 100 light years of us. So if there's anybody on any planets around any

of those stars, our radio transmissions have reached them by now, and they may be

sitting up nights in their observatories watching "I Love Lucy" through their radio

telescopes. The mind boggles!

Nobody thought that.

Saturn. If you look at the sky after sunset you will see Venus is a bit yellow.

Earth is mostly blue- due to all the water, but has large expanses of other colors including green, brown, and white when you include all the land.

Mercury is closest to grey or brown. Mars is red (hence "the Red Planet"). Jupiter is multicolored but mostly brownish. Uranus is light blue. Neptune is startlingly blue. Pluto is kind of brownish-grey.

he does not see the moon do anything he's watching a solar eclipse and possibly going blind

Asteroids, meteors, planetesimals (Like Pluto), natural satellites (moons), and dust are part of the Solar system that are not planets.

It is not necessarily any size, as 0.123 solar masses is a measure of mass rather than size. The size of an object of a given mass can vary depending on the object's density.

then it would hardly have vegetation and human life would not exist

None in our Solar System. Venus takes 224 days for one orbit.

NO! A solar system is a star or star pair with things like planets, moons, asteroids, meteors, and dwarf planets orbiting around that star or star pair. In OUR solar system we have only one star, "The Sun".

Our Sun, although with the amount of debris in Earth orbit...

Solar system will take electricity.

Only the Earth, as far as we currently know.

Saturn is the second largest planet in the Solar System and exhibits a large ring structure.
