• 1 star $({\pmb{\mathbb{\text{\red{The Sun}}}})}$
• 8 planets$({\pmb{\mathbb{\text{\red{Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune}}}})}$
• 5 dwarf planets $({\pmb{\mathbb{\text{\red{Pluto, Ceres, Haumea, Makemake, and Eris}}}})}$
• 181${\pmb{\mathbb{\text{\red{moons}}}}}$

Answer 2

Answer:

The Sun along with the eight planets, their moons, asteroids, comets and meteors constitute our solar system.

The Sun along with the eight planets, their moons, asteroids, comets and meteors constitute our solar system.Sun is the biggest star of our solar system. The diameter of the Sun is 109 times the diameter of the earth. Sun is approximately 300000 times heavier than the earth. Sun is a huge bright ball comprising hydrogen and helium gases. It is the primary source of energy. Formation of day and night, change of seasons and formation of rain all these occur because of Sun. The life of all living beings depends upon solar energy.

The life of all living beings depends upon solar energy.A solid heavenly body which revolves around the Sun in a closed circular orbit is called a planet. There are eight planets in all, including the earth. All planets rotate from the west to the east except Venus, which rotates from east to west. Due to their different speeds, the position of the planets with respect to the earth changes every day. In Indian, the planets are called Graha. The small pieces of rocks or metals which revolve around the Sun between Mars and Jupiter are called asteroids.

In the Solar System, there are three types of Planets:

1. Mercury [Budha]: It is the first planet in the solar system and is closest to the Sun. Because’ of its closeness to the sun, it is one of the hottest planets in the solar system. The surface features of mercury are similar to that of the moon. It neither has water nor atmosphere. Because of his extremely high temperature, lack of water and atmosphere, life is not possible.

2. Venus [Shukraj]: It is the second planet from the sun. Except for the sun, and the moon, it outshines all the heavenly bodies and hence, regarded as the brightest and hottest planet. It appears as an evening star, just above the western horizon for 292 days. After this, it appears as a morning star for another 292 days in the eastern horizon. In spite of the fact that Venice is the second in distance from the sun, as compared to Mercury, it is the brightest due to the cloudy atmosphere of carbon dioxide. This cover reflects more than of the sunlight falling on its surface. The mass of Venus is 0.8 times the mass of the earth. However, its’size is almost similar to that of the Earth.

3. Earth [Prithvi]: Earth is the third planet from the Sun. The tilted axis of rotation of the earth is always in the same direction. Due to this tilt in the axis of rotation, the position of the northern and southern hemispheres of the Earth towards the sun keeps on changing, throughout the year.

4. Mars [ Mangal]: It appears like a red star and hence, it is sometimes called the Red Planet. There are two moons revolving around it. namely, Phobos and Deimos. Both these moons are very close to the surface of the Mars and are less than 20 km in diameter.

5. Jupiter [Guru or Brihaspati]: It is the largest planet in the solar system. One special feature of this planet is a great red spot, which is 30000 km long and 13000 km wide. It is known to have 61 moons. It has a faint ring around its equatorial plane.

6. Saturn [Shani]: Saturn is surrounded by three flat rings, which consist of rocks whose size may vary from a speck to a few kilometres in diameter. Among them, the second ring B is the brightest. It has 31 known moons, the largest being Titan. Besides, in Vedic astrology, Rahu and Ketu are known as invisible planets or shadowy planets.
