Earth's atmosphere is rich in nitrogen and oxygen. Thus, Earth became included in the list of planets,  whereas Cosmo Casino Online Sun and Moon were excluded.

A net angular momentum can be induced by the individual angular momentum contributions of accreted objects. Because of its thick, toxic atmosphere that's made of sulfuric acid clouds, Venus is an extreme example of the greenhouse effect. All of the Solar System planets except Mercury  have substantial atmospheres because their gravity is strong enough to keep gases close to the surface. Main article: Planetary differentiation.

Of the eight currently recognized planets of the solar system, the inner four, from Mercury to Mars, are called terrestrial planets ; those from Jupiter to Neptune are called giant planets or Jovian planets.
Between these two main groups is a belt of numerous small bodies called asteroids. After Ceres and other larger asteroids were discovered in the early 19th century, the bodies in this class were also referred to as minor planets or planetoids, but the term asteroid is now used most widely.
The planets and other objects that circle the Sun are thought to have formed when part of an interstellar cloud of gas and dust collapsed under its own gravitational attraction and formed a disk-shaped nebula.
See solar system: Origin of the solar system. Astronomers have long wondered if this process of planetary formation could have accompanied the birth of stars other than the Sun.
Instead, astronomers concentrated on attempting to observe them indirectly through the gravitational effects they exert on their parent stars.
After decades of searching for such extrasolar planets , astronomers in the early s indirectly identified three planets circling a pulsar i.
The first discovery of a planet revolving around a star more like the Sun came in with the announcement of the existence of a massive planet orbiting the star 51 Pegasi.
In the first 15 years after these initial discoveries, about planets around other stars were known, and in astronomers obtained the first direct infrared images of what were interpreted to be extrasolar planets.
In size these objects range from a fraction of the mass of Jupiter to more than a dozen times its mass. Astronomers have yet to develop a rigorous, generally accepted definition of planet that will successfully accommodate extrasolar planets and distinguish them from bodies that are more starlike in character e.

There are 8 planets and over moons in the solar system. Of these, the planets Venus, Earth, Mars, Jupiter,…. Rivers and maybe even oceans existed.
Although Mars' atmosphere is too thin for liquid water to exist on the surface for any length of time, remnants of that wetter Mars still exist today.
Sheets of water ice the size of California lie beneath Mars' surface, and at both poles are ice caps made in part of frozen water.
In July , scientists revealed that they had found evidence of a liquid lake beneath the surface of the southern pole's ice cap. It's the first example of a persistent body of water on the Red Planet.
Scientists also think ancient Mars would have had the conditions to support life like bacteria and other microbes.
Hope that signs of this past life — and the possibility of even current lifeforms — may exist on the Red Planet has driven numerous space exploration missions and Mars is now one of the most explored planets in the solar system.
The fifth planet from the sun, Jupiter is a giant gas world that is the most massive planet in our solar system — more than twice as massive as all the other planets combined, according to NASA.
Its swirling clouds are colorful due to different types of trace gases. And a major feature in its swirling clouds is the Great Red Spot, a giant storm more than 10, miles wide.
It has raged at more than mph for the last years, at least. Jupiter has a strong magnetic field, and with 75 moons, it looks a bit like a miniature solar system.
The sixth planet from the sun, Saturn is known most for its rings. When polymath Galileo Galilei first studied Saturn in the early s, he thought it was an object with three parts: a planet and two large moons on either side.
Not knowing he was seeing a planet with rings, the stumped astronomer entered a small drawing — a symbol with one large circle and two smaller ones — in his notebook, as a noun in a sentence describing his discovery.
More than 40 years later, Christiaan Huygens proposed that they were rings. The rings are made of ice and rock and scientists are not yet sure how they formed.
The gaseous planet is mostly hydrogen and helium and has numerous moons. The seventh planet from the sun, Uranus is an oddball.
It has clouds made of hydrogen sulfide, the same chemical that makes rotten eggs smell so foul. It rotates from east to west like Venus.
But unlike Venus or any other planet, its equator is nearly at right angles to its orbit — it basically orbits on its side.
Astronomers believe an object twice the size of Earth collided with Uranus roughly 4 billion years ago, causing Uranus to tilt.
That tilt causes extreme seasons that last plus years, and the sun beats down on one pole or the other for 84 Earth-years at a time. The collision is also thought to have knocked rock and ice into Uranus' orbit.
These later became some of the planet's 27 moons. Methane in the atmosphere gives Uranus its blue-green tint. It also has 13 sets of faint rings. The eighth planet from the sun, Neptune is about the size of Uranus and is known for supersonic strong winds.
Neptune is far out and cold. The planet is more than 30 times as far from the sun as Earth. Neptune was the first planet predicted to exist by using math, before it was visually detected.
Irregularities in the orbit of Uranus led French astronomer Alexis Bouvard to suggest some other planet might be exerting a gravitational tug.
German astronomer Johann Galle used calculations to help find Neptune in a telescope. Neptune is about 17 times as massive as Earth and has a rocky core.
Once the ninth planet from the sun, Pluto is unlike other planets in many respects. From until early , Pluto had actually been the eighth planet from the sun.
Then, on Feb. It's a cold, rocky world with a tenuous atmosphere. Scientists thought it might be nothing more than a hunk of rock on the outskirts of the solar system.
Pluto is a very active ice world that's covered in glaciers, mountains of ice water, icy dunes and possibly even cryovolcanoes that erupt icy lava made of water, methane or ammonia.
In , researchers proposed the possible existence of a ninth planet, for now dubbed " Planet Nine " or Planet X. The planet is estimated to be about 10 times the mass of Earth and to orbit the sun between and 1, times farther than the orbit of the Earth.
Scientists have not actually seen Planet Nine. They inferred its existence by its gravitational effects on other objects in the Kuiper Belt, a region at the fringe of the solar system that is home to icy rocks left over from the birth of the solar system.
Also called trans-Neptunian objects, these Kuiper Belt objects have highly elliptical or oval orbits that align in the same direction.
The research is based on mathematical models and computer simulations using observations of six other smaller Kuiper Belt Objects with orbits that aligned in a similar matter.
A recent hypothesis proposed September on the pre-print server arXiv suggests Planet Nine might not be a planet at all.
Instead, Jaku Scholtz of Durham University and James Unwin of the University of Illinois at Chicago speculate it could be a primordial black hole that formed soon after the Big Bang and that our solar system later captured, according to Newsweek.
Unlike black holes that form from the collapse of giant stars, primordial black holes are thought to have formed from gravitational perturbations less than a second after the Big Bang, and this one would be so small 5 centimeters in diameter that it would be challenging to detect.
