Some Relatives Facts About Our Solar System
Some Relatives Facts About our Solar System. The Solar System is the gravitationally bound planetary system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, such as the five dwarf planets and small Solar System bodies.
In Our Solar System :
Largest Planet - Jupiter
Smallest Planet - Mercury
Brightest Planet - Venus
Hottest Planet - Venus
Coldest Planet - Pluto
Fastest Planet - Mercury
Planet Fastest From the Sun - Pluto (most of the time) & Neptune (some time)
[ Note : It is Due to the fact that pluto's orbiting path is highly elliptical. So when it comes closest to the sun (4.44 billion km. away),Neptune Become the farthest (4.54 billion km. away), Neptune becomes the farthest (4.54 billion km. away) planet. Planet Nearest to the earth : Venus. ]
The Solar System has formed approximately 4.6 billion years ago and consists of the Sun, planets, dwarf planets and other astronomical objects bound in its orbit. The formation was caused by the collapse of a giant molecular cloud, the mass at the center collecting to form the Sun and a flat disk of dust around it which the planets and other bodies would eventually be formed from.

➤ 99.86% of the system’s mass is found in the Sun and the majority of the remaining 0.14% is contained within the solar system’s eight planets.
➤ The four smaller inner planets, also known as the “terrestrial planets” (Mercury, Venus, Earth, and Mars), are primarily composed of rock and metal.
➤ The four outer planets, also known as the “gas giants” (Jupiter, Saturn, Uranus, and Neptune), are substantially larger and more massive than the inner planets.
➤ The two innermost gas giants, Jupiter and Saturn, are the larger of the four and are composed mainly of hydrogen and helium.

➤ The two outermost gas giants, Uranus and Neptune, are composed largely of ices, (water, ammonia and methane) and are sometimes also referred to as the “ice giants“.
➤ Other objects of note in the Solar System are the dwarf planets (Ceres, Pluto, Haumea, Makemake & Eris), moons, asteroids, the asteroid belt, comets and the Kuiper belt.
➤ The Earth’s rotation is gradually slowing.
This deceleration is happening almost imperceptibly, at approximately 17 milliseconds per hundred years, although the rate at which it occurs is not perfectly uniform. This has the effect of lengthening our days, but it happens so slowly that it could be as much as 140 million years before the length of a day will have increased to 25 hours.
➤ The Earth was once believed to be the centre of the universe.
Due to the apparent movements of the Sun and planets in relation to their viewpoint, ancient scientists insisted that the Earth remained static, whilst other celestial bodies travelled in circular orbits around it.
➤ Eventually, the view that the Sun was at the centre of the universe was postulated by Copernicus, though this is also not the case.
➤ Earth has a powerful magnetic field.
➤ This phenomenon is caused by the nickel-iron core of the planet, coupled with its rapid rotation. This field protects the Earth from the effects of solar wind.
➤ There is only one natural satellite of the planet Earth.
➤ As a percentage of the size of the body it orbits, the Moon is the largest satellite of any planet in our solar system. In real terms, however, it is only the fifth largest natural satellite.
➤ Earth is the only planet not named after a god.
➤ The other seven planets in our solar system are all named after Roman gods or goddesses. Although only Mercury, Venus, Mars, Jupiter and Saturn were named during ancient times, because they were visible to the naked eye, the Roman method of naming planets was retained after the discovery of Uranus and Neptune.
➤ The Earth is the densest planet in the Solar System.
➤ This varies according to the part of the planet; for example, the metallic core is denser than the crust. The average density of the Earth is approximately 5.52 grams per cubic centimetre.
