Physics Of The Solar System

There are many differences among our planets and moons in our Solar System. The geologic activity, composition, interior structure, magnetic field, and atmosphere are all factors that help give these planets and moons there identity. We have sent probes over the years to help examine these properties.

"Our solar system consists of one star and some debris," said Carl Sagan. There are many differences and similarities between the Inner and Outer planets. Our solar system is comprised of the Sun being in the middle, then followed by planets rotating it. The planets which orbit the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. The Inner planets are very different from Outer planets and the Outer planets are completely different from Inner planets, but both are very similar in many ways. Our planets in the solar system have many similarities and differences.

The solar system was created 4.6 billion years ago by a gravitational collapse. A solar system is a star that has planets, moons, asteroids, comets, and meteoroids travel around it. The solar system contains eight known planets which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Neptune. There is around several hundred dwarf plants but only five are currently recognized. The solar system has about 181 moons which orbit around the planets in the solar system. There is also about 150 million asteroids and 3,406 comets also in the solar system.

As technology improves it is even more likely that we will discover more about our solar system. A great current example of this is the claim of ‘Planet X’. Researchers say that there is possibly another planet in our solar system that orbits beyond Neptune but is large in size. Two scientists recently announced evidence that a body nearly the size of Neptune that orbits the sun every 15,000 years. Since it has never been seen, because it only orbits every 15,000 years, scientists and researchers cannot make a factual claim on the body even though there is strong evidence of its

The reading on terrestrial planets from chapter 6 provides readers with a little insight on the similarities and differences between the planets. These planets include Earth, Venus, Mercury, and Mars. Although these planets have very different properties, they are connected due to their history. There are scientific laws that help people understand, compare, and contrast these planets, such as gravity, chemical composition, and temperature.

The solar system was believed to be formed when a gas cloud and dust in space was disturbed by the explosion of the supernova. The explosion made space waves which squeezed in the cloud of the dust. The Jovian planets include Jupiter, Saturn, Uranus and Neptune. These planets surfaces are not solid. Jovian’s atmosphere in our solar system is mostly made of helium and hydrogen.

As our proto-sun was forming and spinning gases such as hydrogen and helium were pushed to outer rings of the nebula. Dust grains near the sun started to collide and overtime the particles and the collisions grew larger. Furthermore, gravity pulled these some of pieces together at a faster rate and over time this process created small planets or planetesimals . As these planetesimals grew larger they combined and created the planets closest to the sun : Mercury, Venus, Mars and Earth.

If you are interested in planets, then Pluto’s history, similarities the sun, and fun facts are for you!

In this report, I will explaining the properties of objects in our solar system and how they are grouped. Before this investigation, I had barely any knowledge about the properties of planets and objects in our solar system, but I learned valuable information through research from different websites, and discussions within my group and my entire class. My report will answer the question, “How can we group objects in the Solar System according to their properties?”

Mars, also known as the Red Planet, is the fourth planet from the Sun. Mars is the only planet in the Solar System to have abit of similarity to Planet Earth. Although Earth is the only planet in our Solar System to have conditions to have life in abundance. Planet Earth’s position in the Goldilock Zone, which contains plenty water, an atmosphere rich with oxygen and an average temperature of 15℃, life flourishes on Earth with these conditions. Seen on Mars is a bright coloured rust, this rust that Mars is known for is due to iron rich minerals.

Even today, scientists understand very little about the formation of Uranus and Neptune. This made scientists have stated that, "...the possibilities concerning the formation of Uranus and Neptune are almost endless." However, it has been suggested that this planetary system evolved in a very non-conventional manner, as described in the following lines. Planetesimals at the disk's inner edge occasionally passed through gravitational encounters with the outermost giant planet, which calter the planetesimals' orbits. The planets scattered inwards the most of the small icy bodies that they encountered, exchanging angular momentum with the scattered objects so that the planets move outwards in response, preserving the angular momentum of the system.

was forming it was a giant ball made of liquid molten. Over a long period of time asteroids hit

Humans live on a small planet in a tiny part of a vast universe. This part of the universe is called the solar system, and is dominated by a single brilliant star-the sun. The solar system is the earth’s neighbourhood and the planets Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto are the Earth’s neighbours. They all have the same stars in the sky and orbit the same sun.

Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.

Ancient astronomers were able to differentiate between stars and planets, as stars remain relatively fixed over the centuries while planets will move an appreciable amount during a comparatively short time.
