## Dwarf Planets

Updated on 24-Jan-2023 12:48:04
Introduction Astrophysics is the branch of science that gives all information about the universe and our place. The surrounding that covers the total universe is called space. The universe contains all planets, stars, galaxies, and various forms of energy in the universe. Some of them have their illumination among the above. The solar system consists of the sun which is surrounded by the planets such as mercury, venus, earth, mars Jupiter Saturn, and uranium. They revolve around the sun in their path. The knowledge about celestial bodies such as the sun, planets, comets, stars, and galaxies is gathered from the ... Read More

## Difference Between Asteroid and Meteoroid

Updated on 17-Jan-2023 11:09:53
Introduction Astrophysics is the major subject to develop knowledge about celestial objects. The study of the sun, the comets, the stars, asteroids, meteoroids, and galaxies is called astrophysics. The birth of the stars and their life and the end of the stars are studied through this. Asteroids are small celestial objects which orbit around the sun. The orbit of the asteroid is in between Mars and Jupiter. A comet contains small rigid material. This material is covered by substances with high masses. Water, methane, and ammonia are the substances that cover the material. These substances are easily vapourised. It rotates ... Read More

## Difference Between Equinox and Solstice

Updated on 11-Jan-2023 12:15:11
Introduction While orbiting the sun, a planet revolves around itself. The time it takes a planet to orbit itself once is called a period of rotation. The rotation time of the earth is 23 hours and 56 minutes. Therefore, a day on earth is 24 hours. Only the planets in our solar system can survive on the earth we live on. Because it is at the right distance from the sun, the earth has the right temperature, the right source of water, the right atmosphere, and the ozone layer. Life can continue on earth. Due to the reflection of light ... Read More

## Difference Between Stars and Planets

Updated on 13-Oct-2022 11:19:47
Introduction Planets and stars, being astronomical bodies are held together because of their individual gravity. Distinguishing stars from planets is very important to identify them as different astronomical bodies. Most of the stars possess a particular shape and from the Earth, these are deemed to be a size of a mere dot. The speed of a star is another important factor that is greater than the speed of any other object, especially from planets. About stars Stars are significant celestial bodies that have their own energy and light. The components of a star are mainly Helium and ... Read More

## Difference Between Solar Eclipse and Lunar Eclipse

Updated on 13-Oct-2022 11:19:47
Introduction An eclipse can be defined as an event that occurs when one celestial body comes in front of another celestial body and the whole thing can be seen from a third celestial body. The line-up or the alignment of this event has a scientific name; it is called syzygy. Eclipse can be divided mainly into two types, solar and lunar. When the moon comes in between the sun and earth, it creates solar eclipse. On the other hand when the earth itself comes in between moon and sun, lunar eclipse occurs. What is a solar eclipse? Figure ... Read More

## The Escape Velocity of Earth

Updated on 13-Oct-2022 11:19:47
Introduction It is often that we wonder how it is possible for any mass to deny the gravitational pull of the earth. The mass of the earth is $\mathrm{5.972\:\times\:10^24\:kg}$ is quite heavy and based on its mass, its pull will be much stronger in nature. This leads to the question of its possibilities and that provides the answer that the rockets induce the principle of huge velocities that are better known to be escape velocities. With this force exerted, the rockets are able to suppress the high gravitational pull of the earth and travel to outer space. What are ... Read More

## Solar System

Updated on 13-Oct-2022 11:19:47
Introduction The solar system includes several non-steller objects that comprise gases as well as lesser bodies. The sun locates in the center of this system and all the planets are turning around the Sun. The planets are also surrounded by their satellites. Besides this, countless asteroid comets along with different icy bodies are included in the solar system. This system is divided into two different groups’ rocky planets and gas planets. The rocky planets comprise the closest four planets like "Mercury, Venus, Earth, and Mars” which are made of different solid rocks as well as metal. The ... Read More

## Rotation and Revolution

Updated on 13-Oct-2022 11:19:47
Introduction The spinning motion of an object, around its own axis is referred to as rotation. An object's orbital motion that is cantered on any other object is known as the revolution. The earth rotates around itself and produces day and night. This is an example of rotation and when it moves around the Sun in a particular path this is regarded as a revolutionary process. Description of Rotation Based on a centre of a particular object, the rotation is a significant and circular movement. The two most important elements of a rotation are the centre of the whole rotation ... Read More

## Constellations

Introduction Once Shyam and Sita visited their village and went on the roof in the moonless night. They are looking up in the sky and saying that there are several twinkling stars there and they are looking very beautiful. Suddenly Sita asked Shyam from which the stars are made up of and why they are shining? Then Shyam replied that the stars are made up of gasses like Hydrogen, Helium etc. and they are shining because these gasses are doing a reaction called Nuclear fusion from which they are producing light and heat. Again they start looking in the sky ... Read More

## Space Travel Equipment

Updated on 13-Oct-2022 11:19:47
Introduction A significant array of features is needed to be available within a spacecraft to ensure the safety of the crew members. A reliable system is also to be installed within the spacecraft so that it can be operated from any space even from very far from the space. The weight of the system and its equipment are needed to be light. Almost all necessities of an astronaut are to be included also. In case of an emergency, the equipment needs to be used properly. The instruments need to possess the capability of keeping any seek astronaut alive in an ... Read More
