What is the Sun?

The Sun is our home star . Our sun gives valuable energy to us. The Earth has living thing because of the sun light. The sun radiates heat in the form of light and it takes only 8 minutes to reach on Earth, but it can takes 100000 years to transfer energy from Sun’s core to the Sun’s surface and emerge as light. The process of transferring energy from Sun’s Core to the surface of Sun is slower because the energy absorbed by trillions of atoms is reemitted again and again. This energy passes through the dense radiative zone. The Sun Our Only Star In Our Solar System. Nuclear fusion reaction in sun The energy emitted by Sun is from the nuclear fusion reaction which takes place in core. In the core the specific type of nuclear fusion reaction occurs is known as proton-proton fusion . These protons are nothing but the hydrogen nucleus. The protons (hydrogen nucleus) fuse together through series and different steps to form the helium . This reaction process ...

Dwarf Planets in our solar system | Makemake, Haumea, Gonggong

What is the Dwarf Planet? According to the International Astronomical Union, the dwarf planets are the celestial bodies that orbits the sun, has not cleared the neighborhood around its orbit, has enough mass to assume a nearly round shape and is not a moon. The number of dwarf planets in our solar system is unknown. Now the question arises that why the Pluto is not a planet? The Pluto has enough mass to assume a nearly round shape, also orbits the sun but the Pluto has not cleared the neighborhood around its orbit. There are six known dwarf planets, the Pluto demoted as a Dwarf Planet, Eris the reason behind the demotion of the Pluto, Ceres the closest dwarf planet from the sun and from the Earth, the Makemake fourth dwarf planet, the Haumea fifth discovered dwarf planet and the Gonggong sixth dwarf planet with Chinese name. I explained the Pluto, Eris and Ceres in my previous article. 1] Makemake dwarf planet ...

8 Things about Mercury planet | The First planet in our solar system

The Mercury: Inner most planet from the sun. The Mercury planet is smallest planet and innermost planet of our solar system. The name Mercury is after the Greek god Hermes, translated into Latin Mercurius Mercury, He is the god of commerce, the messenger of the gods and mediator between gods and mortals. As the Mercury is the closest planet from the sun, it has the fastest speed of revolution around the sun. Because of the sun’s very strong gravitational force, this gives Mercury speed. The Mercury is speeding along at about 29 miles per second around the sun and completing each orbit in just 88 Earth’s days. The Mercury planet rotates about its axis very slowly, taking nearly 59 Earth days to complete one rotation. As a result, a day on Mercury is about 176 Earth day . The speed of planet gives it the nickname as Swift Planet . The Mercury: Smallest Planet in solar system. ...
