The Solar System

Yes, you would need a specialized space suit to breathe on Saturn. The atmosphere on Saturn is mostly hydrogen and helium, with no oxygen, making it uninhabitable for humans without a self-contained life support system.

The solar system is located within the Milky Way galaxy. The Milky Way is a spiral galaxy that contains our solar system along with billions of other stars, planets, and celestial objects. Our solar system orbits around the center of the Milky Way galaxy along with many other stars.

Valles Marineris is the largest canyon in the solar system, located on Mars. It stretches for over 2,500 miles (4,000 km) in length, up to 7 miles (11 km) in depth, and is up to 120 miles (200 km) wide.

Of what? Mammals? Animals? In terms of absolute size, or relative to their mass? Pose a more accurate question please. However, fun fact: Neanderthal's brains were both heavier and larger, proportional to their body size, than modern humans brains. Bigger isn't always better.

It is composed completely of gas. 82% hydrogen & 18% helium

Gas giants are not solid like rocky planets. They are made up mostly of gases such as hydrogen and helium, with a small solid core at their center. The outer layers of gas giants are composed of thick atmospheres.

Terrestrial planets are solid and gaseous planets are made of gas. Gaseous planets are huge and terrestrial planets are small. Gas giants are far from the sun and terrestrial planets are close to the sun.

We can't say, exactly. Since a solar system is just a system of bodies orbiting around a star (a star with a system orbiting it is called a sun), and there are billions of stars in every galaxy, we don't have nearly enough information to make even an educated guess about solar system size rankings.

The center of our solar system is the Sun, which is primarily made up of hydrogen and helium. These elements undergo nuclear fusion in the Sun's core, producing light, heat, and energy that sustains life on Earth.

Jupiter has high mountain peaks, a thick layer of clouds, is covered with clouds and thunderstorms, is orange and red and it has a strong gravitational field. Jupiter is made out of ammonia, helium, and hydrogen.

Skylab orbited the Earth for approximately six years and operated from May 1973 to July 1979. Its orbit decayed over time, leading to an uncontrolled re-entry into the Earth's atmosphere in 1979.

The core of the Sun is considered to extend from the center to about 0.2 to 0.25 solar radius. It is the hottest part of the Sun and of the Solar System. It has a density of up to 150,000 kg/m³ (150 times the density of liquid water) and a temperature of close to 15,000,000 kelvin (by contrast, the surface of the Sun is close to 6,000 kelvin). The core is made of hot, dense gas in the plasmic state. The core, inside 0.24 solar radius, generates 99% of the fusion power of the Sun.

All of them. A few satellites are tidally locked to their primary (luna for example), but all the planets rotate.

I do not really understand what you are asking but The Dwarf Planet Pluto is the ninth planet from the sun, it is believed that it is not even a planet anymore. Thank you for using wikianswers.com.

No, not all planets in the solar system have moons. Mercury and Venus do not have any moons, while Earth has one moon, Mars has two moons, Jupiter has at least 79 moons, Saturn has at least 83 moons, Uranus has 27 moons, and Neptune has 14 moons.

The Sun is the center of our solar system. There are eight planets that circle the sun, each planet has moons and non-stellar objects. The solar system is believed to have been started 4.6 billion years ago in the Big Bang, a collapse of a giant molecular cloud.

Basically, our solar consits of The sun, the eight planets, stars, moons or satellites of the planets, asteroids, meteors, comets, dust particles.

Jupiter and Saturn consist mostly of hydrogen and helium, yes it is.

Probably not. Our solar system has 8 planets, which is the largest number of confirmed planets in any known system. There is, however, the system orbiting the star HD10180, which as at least 7 planets, possibly as many as 9. This is at a time when we have discovered about 1200 other planetary systems, out of an estimated 100 to 400 billion in our galaxy. The easily leaves room for systems with more than 8 planets. Even the known planetary systems may have other planets that we cannot detect with current technology.

Saturn is interesting, but it's not very important. At least not on a day-to-day basis, or even historically; it's very likely that your life would be completely unchanged if Saturn didn't exist.

No, Mercury is not one of the biggest planets in the solar system. It is the smallest planet in our solar system, with a diameter of about 4,880 kilometers.

Space probes, such as NASA's Voyager and Juno missions, are designed to travel into the solar system to collect information about planets, moons, asteroids, and other celestial bodies. They gather data through sensors and instruments onboard, then transmit it back to Earth for analysis by scientists.

Saturn's extreme cold temperatures, lack of a solid surface for life to exist on, and harsh radiation environment make it unlikely for traditional life forms as we know them to survive. The conditions on Saturn are very hostile and not conducive to supporting life as we know it.

When the sun expands into a red giant it will swallow Mercury and Venus and extinguish life on earth. Actually, earth will be uninhabitable more than a billion years before then.

Then the sun will collapse into a hot, bright white dwarf, and burn for billions of years to come. The mass ejection in the red giant stage will cause the remaining planetary orbits to expand slightly, but none of the outer planets will be lost. Eventually the sun will burn out altogether, perhaps ten billion years hence.

Trillions of years from now, during the black hole era most of the matter in the universe will be inside of black holes. During this time it's conceivable that the solar system will had been swallowed by such a black hole. The expectation is that the sun will have spiraled into the black hole at the center of the galaxy, and long, long after that the Andromeda and Milky Way black holes will coalesce.

The temperature does not drop drastically on all planets, only planets with a thin atmosphere, such as Mars or Mercury. It is because the thick atmosphere traps the heat, and clouds are a bonus, like on Venus, because they trap much more heat than just a thick atmosphere.

On a planet like Mars, which has a very thin atmosphere, it cannot hold on to very much heat in the night side, and a planet like Mercury cannot trap any heat and cannot be shielded from the heat for lack of a real atmosphere.

That is the basic idea. =)

Mercury's temperatures can drop to as cold as 100 K (-279.4) at night, but rise to as high as 700 K (800.6 F) during the day. This is due to the fact that Mercury has no atmosphere. Because of this, it experiences the full force of the Sun during the day and the extreme chill of the universe at night.
