Solar System and its Planets

Our Universe is huge, and it continues to enchant us all the time. The remarkable thing is that topics as well as GK questions and answers on the Solar System and the Universe always turn out to be crucial in many ways. The list of planets present in the Solar System is Mercury, Earth, Venus, Jupiter, Mars, Uranus, Saturn, and Neptune. Students, beginning from the lower standard to the higher standard, are asked to answer various questions on the Solar System.

The Solar System comprises 8 planets, the Sun, comets, 180 satellites, asteroids, and meteors. According to the scientists, the Sun encompasses moving clouds of gases, known as Nebula, and the Sun, as well as its planets, got formed from this cloud-only. They were formed due to the force of gravity. For many, many years, these balls comprising gas and dust move around the Sun. Due to the weight and mass of the Sun, it can control the planets’ movement, and this force that the Sun applies is called the force of gravity.

Students are habitually needed to answer questions about planets, and so, when you wish to answer the quiz on Solar System with answers, then you need to know about the following:

The Sun

Till now, the Sun is considered the biggest object that is present in the Solar System, and it comprises nearly 99.8% of the mass of the Solar System. The Sun is known as a hot ball comprising glowing gases. Due to its gravity, the Sun can hold the Solar System together. Additionally, it can keep everything right in its orbit. When planets orbit the Sun in an oval-shaped path, then it is known as an ellipse. When there is an absence of the energy of the Sun, then there wouldn’t be any life on earth.

What are Dwarf Planets?

Dwarf planets are objects that have huge similarities to planets of the Solar System. Nonetheless, they are not sufficiently large for being qualified as planets because they have failed to clear their orbital area. Commonly, there are five dwarf planets present in the Solar System, and they are Haumea, Makemake, Eris, Ceres, and Pluto.

What are called Comets?

Comets are called dirty snowballs, and they comprise rock and ice. When the orbit of a comet comes closer to the Sun, then the ice turns into a gas, and it shoots out of the sunlit side of the comet. The solar wind carries it outward for turning into a big tail.

The System 

It is pretty natural for students to complete Solar System questions, and some common topics are:

• Kuiper Belt: The Kuiper belt is acknowledged as many small bodies that live out the planets’ orbit. The objects present in the Kuiper belt encompass ices like methane, water, and ammonia.

• Asteroid Belt: It is a region that happens between the planets; Jupiter and Mars. Here, in this region, many rocky objects do orbit around the Sun, and they range in sizes from a small dust-like particle to some dwarf planet, like Ceres.

Some Facts about our Solar System

An exclusive knowledge about the Solar System is a must for every person as our Universe has countless galaxies. A galaxy is acknowledged as a big assemblage of stars, and they are held together due to the attraction of gravity.

Our galaxy is known as the Akash Ganga or the Milky Way Galaxy. This is spiral in shape and comprises more than 100 billion stars that revolve and rotate about their centre. The closest galaxy is known as Andromeda.

Our Solar System takes nearly 230 million years to complete one orbit of the galactic centre. The Astronomical Unit is considered the mean distance that covers the Sun and the Earth, and one light-year is equivalent to 60,000 Astronomical Units. 

Light Year is considered the distance that the light covers in just one year at a speed of 3105 kilometres per second.

Edwin Hubble demonstrated the presence of galaxies beyond the Akash Ganga in the year 1924. He also proved that galaxies fly away from one another, and when they are farther, they tend to be faster. And this means our Universe is growing similar to a balloon that is blown up.
