The Solar System

The largest small body found in the solar system is the dwarf planet Ceres, which is located in the asteroid belt between Mars and Jupiter. It is about 590 miles (940 kilometers) in diameter and makes up about one third of the total mass of all objects in the asteroid belt.

In theory, the gravity of each object in the universe affects every other object in the universe. If you do the math, you will see that the effects can be so small for one object that they vanish, for all intents and purposes, over huge distances. But the combined effect of gravity from every single bit of mass in the universe is another matter. Some theorize that inertia may be a result of this cumulative affect. Regarding the solar system, the sun is massive enough to keep all of the planets and countless other smaller bodies in orbit. The planets and other bodies are kept in place because their inertia, their tendency to go in a straight line, is balanced by their gravitational pull toward the sun. In a sense, everything in orbit is "falling" toward the sun, but "missing" it because the orbital velocity keeps them "wanting" to move in a straight line.

If this is from Florida Focus, and in general terms, Modern astronomers would suggest the Sun is not the exact center of the Solar System, but would agree that the Sun is not revolving around Earth.

Well to put it in simple terms, The Hierarchy of the universe would go in this order.

The Universe being the biggest and containing everything would be at the top,

next would come galaxies as these are clusters of stars millions of light years across.

A Nebula would follow, the remnants of an exploded dead star, and also the birthing ground of new stars.

A solar system would be next because it contains not just the star (or stars in a binary or ternary system) but also all the planets meteors asteroid's and planets.

Then would come the star itself in Our Case the Sun and then the planets and moons and then everything smaller than that from an asteroid to a particle of dust or ice.

As far as is known, there is no life anywhere, on any planet, satellite, asteroid, meteoroid, comet, star, quasar, nebula, constellation, asterism, space probe, UFO, interstellar cloud, or field of any kind, except for the Earth and the International Space Station.

Ink relies on gravity to make it flow down and out of the pen. When you are in space, there is no constant gravity so the ink doesn't flow. A pencil doesn't have that problem, it works regardless of gravity. Just put pencil on the page and push it around and the graphite tip will leave a mark.

Earth is the only habitable planet in our solar system. As for the rest of the universe, it's highly probable that there are planets that can sustain life but compared to the billions of other objects in that vast emptiness, it's a difficult task to even find any.

Mars because it has no life ,because it is to close to the sun.

Luxray8910 says: Actually, Mercury is the closest planet to the sun. But Mars is red, and it is not really possible for Plants or any Living Organism to live on Mars, and that is why it was often referred to the Dead Planet.

To find whats in it. We are exploring the solar system to gain knowledge about it's contents. Many scientists are intrigued by the solar system and it's many planets and stars, therefore want to learn more about them.

The orbits of the planets lie in nearly the same plane because they formed from a rotating disk of gas and dust around the young Sun, known as the solar nebula. As gravity caused material in the disk to clump together, it formed into the planets we see today, all orbiting in a flat plane due to the conservation of angular momentum.

Every member of the solar system revolves around some other member in an elliptical orbit.

From time to time, other bodies ... such as non-periodic comets for example ... pass through

the solar system and continue on their way. Those are not members of the solar system,

just visitors.

Well, it is obviously Earth. But if you meant the nearest planet (excluding Earth), it varies from time to time; at their closest approaches Venus is around 45,000,000 km away to the Earth and Mars is around 80,000,000 km away from the Earth. But they aren't always or even usually at their closest approach to Earth. Whether Earth and the Moon are closer to Venus or to Mars depends on the three planets' relative positions in their orbits. When Mars is at opposition it is only about 80 million km from Earth and the Moon (60 million km if the opposition occurs at Mars' perihelion), and when Venus Is at superior conjunction it is 225 million km away.

The planet Venus is sometimes referred to as the "elegant planet" due to its visible brightness and its graceful movements in the sky as seen from Earth. It is also often associated with beauty and femininity in mythology.

Yes, the sun is the largest object in our solar system. It contains over 99% of the total mass of the entire system.

Smoke particles in the air can deposit on solar panels, reducing their efficiency by blocking sunlight from reaching the surface. Additionally, smoke can decrease the air quality, leading to higher levels of particulate matter that can settle on solar panels and reduce their performance. Finally, smoke can also contribute to the overall climate change, which can have long-term effects on solar energy production.

Of the four inner terrestrial planets, Mars is the furthest from the sun. This is the outermost of the four inner planets.

Yes, objects like asteroids or comets from interstellar space can potentially collide with Earth and cause significant impact. Additionally, cosmic events such as supernovae explosions or gamma-ray bursts from distant sources could also affect Earth's atmosphere or climate.

Mars and Jupiter have 343 million mi (552 million km) of space between them, so there are lots of things in between the two planets. However, the main thing between Mars and Jupiter is the asteroid belt.

There is only one, the Sun. But the nearest star to earth other than the sun is Proxima Centauri.

About 30 years ago, there was a theory that there was a second star, an invisibly-dim brown dwarf, in a highly-elliptical several-million-year orbit around the Sun. This mini-star was named "Nemesis", and the theory was that as Nemesis passed through the Oort Cloud, its gravity would disrupt many of the proto-cometary bodies that we believe may be out there. This would, among other things, explain the periodicity of the mass extinction events that happen every 30 million years or so. Hence, the name "Nemesis".

But the Hubble Space Telescope would have been able to detect it, and the math didn't work out for the periodic extinctions, so most astronomers accept that there is only one star in our solar system; our Sun.

The inner planets, also known as terrestrial planets, are Mercury, Venus, Earth, and Mars. These planets are closest to the Sun in our solar system and are primarily composed of rock and metal. They have solid surfaces and thin atmospheres compared to the outer gas giants.

The largest planet in our solar system is Jupiter.

Mercury, Venus, Earth, and Mars are the rocky planets in our solar system. These planets are predominantly composed of silicate rocks and metals, with solid surfaces and relatively thin or non-existent atmospheres.
