The Solar System

No, space refers to the vast emptiness beyond Earth that contains stars, planets, and other celestial bodies. The solar system is a specific region of space that includes our sun, along with the planets and other objects that orbit it, such as Earth, Mars, and Jupiter.

Mercury has an equatorial diameter of 3.48 times 10^3 kilometers.

Dead and decomposed trees are part of the biosphere component of the Earth system. As organic matter, they play a crucial role in nutrient cycling and provide habitat for various organisms.

Venus was once thought to be two separate planets because of its phases when observed from Earth. This led to the misconception that there were two distinct bodies - "Morning Star" when it appeared in the morning and "Evening Star" when it appeared in the evening.

There are on the order of 100,000,000,000 (one hundred billion) galaxies in the universe, as far as current telescopes can detect. Some of these galaxies may hold up to 100,000,000,000 stars, but most galaxies probably contain at least 10,000,000,000 stars. Young galaxies under 2,000,000,000 years old may not have formed many solar systems yet, while very old galaxies more than 10,000,000,000 years old may have very few galaxies left. For the galaxies of middle age, as many as 1/4 of the stars may possess solar systems.

My comment: While the answer above is true based upon current knowledge, it is essentially incorrect.

The answer to your question is: ONE. Our Sun is named Sol - and the system of planets and other objects orbiting it are referred is referred to as "Solar", being of Sol. So other planetary systems exist, but they are not "Solar"...

Comment: The above is incorrect, the answer above is for our known universe not the entire universe. There may be even more. The universe doesn't have a known edge, or a wall so, it's really hard to say.

It would be possible to even say infinite, though scientists really hate the word infinite ;)

Some elements and compounds require extremely low temperatures to freeze. For example, hydrogen freezes at 14 K, which is only 14 degrees above absolute zero and equal to about 259 degrees below zero C or 434 degrees below zero F, and it boils at about 20.3 K (-252.9° C or -423.2° F).

Another example is methane. That seems to be in liquid form on the moon Titan.

Also temperatures are higher inside the gas giants than they are on the surface. Pressure also increases inside these planets. So we believe the liquid hydrogen inside Jupiter is in fact at a high temperature and pressure. The overall result is that it is a liquid.

Remember that temperatures and pressures inside planets (and moons to some extent) can be much higher than on the surface.

For example, scientists think there may be an "ocean " of liquid water under the thick ice that covers Jupiter's moon Europa.

Moon, Milky way galaxy, mars and many others.

Objects are attracted to other objects. now this is much more complex than that but I neither have the technical knowledge or time to truly explain all that. So because particles are attracted to each other the more mass an object has the more it pulls or attracts other objects, we call this force gravity. Objects such as planets that are orbiting other things (typically stars due to their massive size) are in a place where the force of gravity is not allowing them to escape but not entirely pulling them in.

Stars (like the Sun) and planets form from fast-swirling clouds of dust. When their force of gravity is great enough, the swirls clump together into a spherical ball. That does not make them stop spinning or stop them from orbiting the Sun.

We see that there is very little to make the spinning, orbiting planets slow their spins or orbits.

A "Day" relates to the rotation of the planet. The giant Saturn spins around, or rotates, once every 10 hours and 45 minutes. So it's "Day" is only 10 hours 45 minutes (earth hours) long. Whereas Earth spins slower so its day is longer.

On Venus it rains sulfuric acid, although due to the heat it never reaches the ground but vaporises about 5 miles before the surface of the planet.

That would be a galaxy. Our solar system is part of the Milky Way galaxy, which contains billions of stars, planets, and other celestial objects.

An asteroid is a ball of rock that stays in space. If an asteroid burns up in the atmosphere as it heads towards Earth it is called a meteor. If it actually stays intact and impacts with the ground it is a meteorite.

The gas substances that compose the majority of the solar system are hydrogen and helium. These elements make up about 98% of the total mass of the solar system, with hydrogen being the most abundant. Other gases like oxygen, carbon, and nitrogen are present in smaller amounts.

The three types of small bodies in the solar system are asteroids, comets, and meteoroids. Asteroids are rocky objects found mostly in the asteroid belt between Mars and Jupiter, comets are icy bodies with tails that form when they approach the sun, and meteoroids are small rocky or metallic fragments that travel through space.

Oval circles in the solar system? Hm you may be talking about the oval lines that are shown in a simple edited solar system image. The oval like lines are the planets orbit trial in which they revolve around the sun.

A new moon phase is happening when the moon is aligned between the Earth and the Sun. During this phase, the side of the moon that is illuminated by the Sun is facing away from Earth, making the moon appear dark or invisible from our perspective.

1. Mercury - 5.43 gr/cm3
2. Venus - 5.24 gr/cm3
3. Earth - 5.515 gr/cm3
4. Mars - 3.940 gr/cm3
5. Jupiter - 1.33 gr/cm3
6. Saturn - 0.70 gr/cm3
7. Uranus - 1.30 gr/cm3
8. Neptune - 1.76 gr/cm3

there are many reasons.

-pluto is way smaller

-pluto has a very elliptical orbit that crosses Neptune's path.

-pluto has an orbit that is tilted about 17 degrees.

these are only a few of the reasons. hope it helps!

Earth is the only planet in our solar system known to have significant bodies of liquid water on its surface. Some of Jupiter's moons, like Europa, Ganymede, and Callisto, are believed to have subsurface oceans of liquid water.

Saturn is the least dense planet because it is primarily made up of hydrogen and helium, which are the two lightest elements. These elements have low densities compared to the rocky materials that make up the inner planets like Earth. Additionally, Saturn's large size and low mass contribute to its overall low density.

About 120 planets are in our solar system.

There are 8 planets in our solar system. They are Earth, Mars, Venus, Mercury, Jupiter, Saturn, Neptune and Uranus. Originally there were many more, but they could have been thrown out of the solar system or have crashed into the Sun or another planet.

1. Earth
2. Jupiter
3. Mars

A solar system is smaller. There are billions of solar systems in a single galaxy.
Each star is a solar system. (some have planets, some don't)
When you look at the sky at night, every star is a solar system and all of them are part of the Milky Way galaxy.

A galaxy cluster is a group of galaxies.
