Complete information and interesting facts about Solar System

Complete information and interesting facts about Solar System. The Solar System, which we can call our home, is our identity in space by which we are known in the entire galaxy. In today's article, we will talk about this solar system Will know

When you look at the sky at night, then the thought that must come in your mind is that what are all these stars, planets and moons? How are they made and what is the science behind them?

Whatever you have read about them in books, but when you really see them in the sky with your eyes, then you will have different thoughts in your mind which may not have any meaning with books.

Today in this article we will talk about the solar system as well as all of its planets. Our solar system which is bound in the limits of the sun itself, contains so many secrets inside itself that it can take us many years to understand them.

The Solar System or Solar System is 4 and a half billion years old, it shows the boundary of the Sun, as far as the gravity of the Sun is there, we consider the boundary of the Solar System.

If we really see it, it is much bigger than we think, it consists of eight planets and five dwarf planets. Today, we know more about our solar system than any research and research we have done about the universe.

What's in the solar system

Our solar system is very large with 1 sun, 8 planets, 5 dwarf planets, 181 moons, 555,300 meteorites and about 3 thousand comets. All these things are tied due to the gravity of the Sun and revolve around it. Generally, planets revolve around the Sun.

1. Sun - The Sun is the basis of our Solar System, we can also call it the God of the Solar System, because of this the Solar System is sustainable. This is the only star whose energy we live by. It occupies 99.8 percent of the entire solar system.


8 planets - There are eight planets in the solar system which are as follows - Mercury, Venus, Prithvi (Earth), Mars (Mars), Jupiter (Jupiter), Saturn (Saturn), Arun (Uranus), Neptune.
5 dwarf planets - (Pluto, Ceres, Haumea, Makemake, and Eris)

181 Moon

555,300 meteorites

3,100 Comets

The orbits

The orbits of the planets are Ellipse shaped, with the Sun in one focus, although the orbit of Mercury is almost circular. The orbits of all the planets are in almost the same plane, which is called the ecliptic

This ecliptic is defined by the perimeter of the Earth's orbit (in other words the eclipse of the ecliptic and the ellipse of the Earth is the same). This ecliptic is 8 degrees above the equator of the Sun.

All planets except Venus, Uranus and Pluto rotate in the same direction but Venus, Uranus and Pluto rotate in the opposite direction.

Mercury image

Mercury is the nearest planet to the Sun and is at number eight by mass. Mercury is smaller than Diameter and smaller than Titan moon but is doubling in mass. It is also the smallest planet in the Solar System, although it is not the hottest planet in the Solar System even after being closest to the Sun.

Mercury - Solar System facts

It takes 88 days to make one revolution of the Sun. It is made of iron and zinc. So far, two spacecraft, Mariner 10 and Messenger Mercury, have left. Mariner - 10 has visited this planet thrice between 1974 and 1975.

Orbit: 57,910,000 km (0.38 AU) from the Sun, diameter: 4880 km, mass: 3.30e23 kg

Mercury's orbit is more eccentric, its distance from the Sun ranges from 46,000,000 km (perihelion) to 70,000,000 km (aphelion). When Mercury is close to the Sun, then its motion is very slow.

The temperature on the surface of Mercury goes from 90 deg Kelvin (1 Degree Celsius = 274.15 Kelvin) to 700 deg Kelvin. The temperature on Venus is warmer than this but is permanent.

There is a moon-like crater (landfill) on the surface of Mercury. The surface of Mercury is permanent, there is no activity in the layers on it. The density of Mercury is 5.43 g / cm and it is the highest density body after Earth.

Venus is a planet in our solar system that is ranked second in the order of closest distance from the Sun, Mercury on the first. Venus is almost similar in size to our planet Earth.

If you see in the sky at night, which is the most brightly glowing object after the moon, then it is Venus. Its circumambulation path is 108,200,000 km long. Its diameter is 12,103 km. Venus is the hottest planet in the solar system.

Venus - Solar System facts 

Orbit: 0.72 AU or 108,200,000 km (from Sun), Diameter: 12,103.6 km, Mass: 4.869e24 kg

The rotation of Venus is peculiar, it is quite slow. Its one day is equal to 243 Earth days which is more than a year of Venus. The rotation of Venus and its orbit is such that only one surface of Venus is visible from the Earth.

After the Sun and the Moon, Venus is the most brilliant object in our night sky! Venus rotates clockwise in our solar system due to its very slow rotation, experts believe that this planet must have hit someone in the past which has changed its rotation speed!


Earth image

Earth planet comes third in distance from the Sun. It is also a blue planet with a lot of water content. These are the only planets where life is. The planet Earth is the only planet whose English name is not from Greek / Roman mythology.

Its distance from the Sun is considered to be a unit called the astronomical unit or AU (Astronomical Unit). 1 AU means 150 million kilometers.

Earth - Solar System facts 

Class 1.00: 149,600,000 km (AU, from Sun), Diameter: 12,756.3 km, Mass: 5.972e24 kg

The age of the earth is from 4.5 billion years to 4.6 billion years, but the oldest rock of the earth is 4 billion years old, the rocks that are older than 3 billion years are rare. The life of fossils of living animals is less than 3.9 billion years.

There is no evidence of the beginning of life. 70% of the Earth's surface is covered with water. Earth is the only planet on which water is available on the surface in a fluid state.

Earth's atmosphere contains 77% nitrogen, 21% oxygen, and some amount of argon, carbon dioxide and water vapor.

The Earth has only one natural satellite: the moon. Apart from this, there are thousands of thousands of artificial satellites. The asteroid 3753 is Krauthen and the 2002 A A 29 is Earth's companion. Who revolve around the sun with the earth.


Mars image

Mars is the fourth planet from the Sun in the solar system. This planet looks completely red when viewed from the earth. The surface of this planet which is made up of rocks and sand particles.

There are two types of planets in the solar system - "surface planets" which contain land and "gaseous planets" which mostly contain gas. Like Earth, Mars is also a terrestrial planet.

The Mars Seen From Telescope - Picture of Mars - Complete information of the Solar System

Orbit: 1.52: 227,940,000 km (AU from Sun), Diameter: 6794 km, Mass: 6.4219e23 kg

Mariner-4 vehicle was sent on Mars in 1965. After that, apart from Mars 2 which also landed on Mars, many vehicles have been sent. In 1976, two Viking vehicles also landed on Mars.

After 20 years, on 4 July 1997, Marsh Pathfinder landed on Mars. Mangalyaan of India is also studying and setting it in the orbit of Mars.

The average temperature on Mars is 218 degrees Kelvin (-55 degrees Celsius). The surface temperature of Mars varies from 133 degrees Celsius to 27 degrees Celsius.

The landscape on Mars is quite interesting and diverse.

Olympus Mons: The largest mountain in the Solar System, which is 78,000 feet (24 km) high, more than 500 kilometers in diameter at the base.

Tharsis: 10 km high and 4000 km wide and has a large bulge.

Wallace Marineris Valley: a system of valleys 4000 km in length and 10 km deep.
