what is solar system?

Answer 1

The Solar System or solar system[1] comprises the Sun and the retinue of celestial objects gravitationally bound to it: the eight planets, their 162 known moons,[2] three currently identified dwarf planets and their four known moons, and thousands of small bodies. This last category includes asteroids, meteoroids, comets, and interplanetary dust.

The principal component of the Solar System is the Sun or Sol (astronomical symbol ); a main sequence G2 star that contains 99.86% of the system's known mass and dominates it gravitationally.[3] The Sun's large mass gives it an interior density high enough to sustain nuclear fusion, releasing enormous amounts of energy, most of which is radiated into space in the form of electromagnetic radiation including visible light. Jupiter and Saturn are the Sun's two largest orbiting bodiesand account for more than 90% of the system's remaining mass. (The currently hypothetical Oort cloud would also hold a substantial percentage were its existence confirmed).[4]

In broad terms, the charted regions of the Solar System consist of the Sun, four rocky bodies close to it called the terrestrial planets, an inner belt of rocky asteroids, four gas giant planets and an outer belt of small icy bodies known as the Kuiper belt. In order of their distances from the Sun, the planets are Mercury (), Venus (), Earth (), Mars (), Jupiter (), Saturn (), Uranus (), and Neptune (). All planets but two are in turn orbited by natural satellites (usually termed "moons" after Earth's Moon) and every planet past the asteroid belt is encircled by planetary rings of dust and other particles. The planets other than Earth are named after gods and goddesses from Greco-Roman mythology.

From 1930 to 2006, Pluto (), the largest known Kuiper belt object, was considered the Solar System's ninth planet. However, in 2006 the International Astronomical Union (IAU) created an official definition of the term "planet".[5] Under this definition, Pluto is reclassified as a dwarf planet, and there are eight planets in the Solar System. In addition to Pluto, the IAU currently recognizes two other dwarf planets: Ceres (), the largest object in the asteroid belt, and Eris, which lies beyond the Kuiper belt in a region called the scattered disc. Of the known dwarf planets, only Ceres has no moons.

For many years, the Solar System was the only known example of planets in orbit around a star. The discovery in recent years of many extrasolar planets has led to the term "solar system" being applied generically to all the newly discovered systems. Technically, however, it should strictly refer to Earth's system only, as the word "solar" is derived from the Sun's Latin name, Sol. Other such systems are usually referred to by the names of their parent star: "the Alpha Centauri system" or "the 51 Pegasi system".

Answer 2

Our solar system consists of an average star we call the Sun, the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. It includes: the satellites of the planets; numerous comets, asteroids, and meteoroids; and the interplanetary medium. The Sun is the richest source of electromagnetic energy (mostly in the form of heat and light) in the solar system. The Sun's nearest known stellar neighbor is a red dwarf star called Proxima Centauri, at a distance of 4.3 light years away. The whole solar system, together with the local stars visible on a clear night, orbits the center of our home galaxy, a spiral disk of 200 billion stars we call the Milky Way. The Milky Way has two small galaxies orbiting it nearby, which are visible from the southern hemisphere. They are called the Large Magellanic Cloud and the Small Magellanic Cloud. The nearest large galaxy is the Andromeda Galaxy. It is a spiral galaxy like the Milky Way but is 4 times as massive and is 2 million light years away. Our galaxy, one of billions of galaxies known, is traveling through intergalactic spaceThe planets, most of the satellites of the planets and the asteroids revolve around the Sun in the same direction, in nearly circular orbits. When looking down from above the Sun's north pole, the planets orbit in a counter-clockwise direction. The planets orbit the Sun in or near the same plane, called the ecliptic. Pluto is a special case in that its orbit is the most highly inclined (18 degrees) and the most highly elliptical of all the planets. Because of this, for part of its orbit, Pluto is closer to the Sun than is Neptune. The axis of rotation for most of the planets is nearly perpendicular to the ecliptic. The exceptions are Uranus and Pluto, which are tipped on their sides.

*coughs*

Well,.. our ball of gas that's the center of our little area's name was once " Sol", now we call it Sun. Sol was a specific name once upon a time. This movement tht surrounds Sol is Solar System.

Now we go around lableing things Sol and Luna or Sun and Moon,.. even though those were once the names for our specific Star & Satellite. The rest of the universe had Stars and Satellites,.. but as education spread it dumbed down. Now every planet seems to have their own Sun and Moon (not every Planet has only one Star and one Satellite,.. infact some have no Satellites).

But anyways,.. Lunar and Solar use to deal with things connected to OUR Satellite and OUR Star. And there was recognition that some emotional problems were connected to the Lune and plants reactted to the Solar activities.

Aw well,... Now other Stars that have things revolveing around them might end up being labled a Solar System,..

Answer 6

That may be a fault in their computer program. We're finding lots of other planetary systems, with a variety of features. There are few where the planets have highly elliptical orbits. Our early solar system was clearly shaped and stabilized by the formation of Jupiter at a radius where it did not migrate inwards or outwards very much, and thereby stabilized the other planet's orbits. Such a circumstance will not happen all the time, but it may not be too unlikely.

Answer 7

Our sun is named 'Sol.' There is a lot of objects in the space around Sol. The ones that are in orbit around Sol are in the control of Sol's gravity. We call such a relationship a 'system.'

Since this system belongs to Sol we say it is the 'Solar System.' Other orbital systems should be called 'star systems.'

;-D Some people may call other systems 'solar systems' but they are incorrect.

Answer 8

why so you guys have to write alot the answer is so easy no extra words needed.

the solar system is a group of small and large bodies that orbit a central star,

Answer 9

a solar system is a collection of usally sperical bodies (planes) which orbit (go around) a central star/mass. ours solar system consists of the central body which we refer to as the sun but is really just a star and 8 orbiting planets aswell as 1 (possibly 2) smaller dwarf planets

Answer 10

??? What is this question about ? Who can ask such thing? Anyway.
A solar system is a group of rocks and / or ice rotating around a star. That's it. "Our" star is called "sun", all the other stars are suns, too. And the pieces of rock rotating around these are called planets. If that is given, it's called a solar system. If there wouldn't be any planets, but e.g. just 3 suns (such systems do exist) then we call it star system, but not solar system. You see, the name "solar system" also implies, that we are talking about a system with 1 sun only ...
