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…

Introduction The advent of stars takes place from a nebula which is a cloud constructed of gas and dust that facilitate factors of temperatures, pressures, density, and others. It is believed that the transformation of hydrogen into helium leads to the formation of stars. In the situation, when starts occur to appear in a certain…

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…

Introduction The present tutorial intends to include the explanation regarding the concepts of physics such as escape velocity and orbital velocity along with explaining the relationship that lies between these two concepts. The tutorial will further include the definition of escape velocity and orbital velocity in order to build or exemplify the relation these two…

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…

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…

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…

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 5.972×1024kg5.972×1024kg 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…

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…

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…
