Objects in Our Universe

  The Earth Our Home World. The Earth planet is Our Home. The Earth planet is known as Goldilocks Planet . The Earth is at the right distance from the Sun . The Earth is in habitable zone of our solar system. This right distance allows the water in the form of liquid. No too cold and no too hot. So this region where the Earth is formed is called “Goldilocks region”. The Earth is the only planet on which the life evolved. The Earth from its early hot form to became heaven for life is the longest journey. Now the question arises as How the Earth made as the Planet and how oceans are made? Let us talk about this now. 4.5 billion years ago, our solar system takes its shapes and structure as it is now. At that time planets are taking their structures, stable orbit, revolution about its axis, this process is very slow and taken billions of years. The Earth was made with the space dust, debris which are spread when the sun formed and these dust and debris orbiting around the sun. This orbit

  The Venus Planet The planet Venus is the second planet from the sun . The Venus name of planet is named after the beautiful Roman goddess because of planet’s brightness and shinning appearance in the sky. After our moon, Venus is the second brightest object in night sky. The distance from the sun is 108 million km or 67 million miles. The planet is hotter than Mercury Planet because of Venus atmosphere and Venus temperature. The color of the Venus is yellowish but at night it appears as bright white to eyes. The Venus rotates around its axis clockwise, unlikely the other planets in solar system . The Venus rotates around its axis very slowly. The planet takes 243 Earth days to rotate at once around axis and orbit around the sun requires 224.7 Earth days. That means the day of Venus is longer than year. This is the only planet of solar system on which the day is longer than the year . The Venus is closest to the Earth and called as Twins planet. The two planets are nearly the same in

  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.               The Mercury is not the brightest planet to see in the sky with naked eyes. T

        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 generates massive a
