![]() The Greeks named the stars and plotted their positions. Early astronomy was a mix of careful observation of the positions and motions of the heavenly bodies, religion, and astrology. Galileo has been called the "father of modern observational astronomy", the "father of modern physics", the "father of science", and "the father of modern science".Early civilizations, for example, Harappans, Mayans, and ancient Chinese used astronomy to keep track of time, orient their cities, and to try to predict the future. His achievements include improvements to the telescope and consequent astronomical observations and support for Copernicanism. Galileo, was an Italian physicist, mathematician, engineer, astronomer, and philosopher who played a major role in the scientific revolution during the Renaissance. “ Types of planets under the Geophysical Planet Definition (GPD)” By Johns Hopkins APL/Mike Yakovlev – (CC BY-SA 4.Astronomy has been practiced for as long as humans have been looking at the sky and wondering what it all means. “Astronomical Object.” Wikipedia, Wikimedia Foundation, 23 Feb. “Celestial Bodies – Meaning, Classification & Heavenly Bodies Names.” BYJUS, 25 Aug. Therefore, there is no difference between celestial and heavenly bodies. They refer to natural objects in space, such as the Sun, planets, and stars. In brief, celestial bodies and heavenly bodies are synonyms. There is no difference between celestial and heavenly bodies.Moreover, we can classify these bodies into several categories as stars, planets, asteroids, comets, asteroids, etc.ĭifference Between Celestial and Heavenly Bodies.They refer to natural bodies outside of the earth’s atmosphere.Celestial bodies and heavenly bodies are synonyms.Similarities Between Celestial and Heavenly Bodies The term heavenly bodies is just another name for celestial bodies. The Moon is a natural satellite of the earth, and it revolves around the earth due to its gravitational pull. This can be a moon, planet or a machine that orbits a planet. Satellites are objects that revolve around planets. If a meteor reaches the ground and creates a crater, we call it a meteorite. These burn up as they enter the earth, creating streaks in the sky as if a star has fallen. Meteors are small bodies of matter from outer space that enter the atmosphere of the earth. Most of these are found between the orbits of Mars and Jupiter, in an area named the asteroid belt. Moreover, they have irregular shapes and are made of metals or minerals. AsteroidsĪsteroids are small rocky bodies that orbit the Sun. As the gas and dust in the coma flow freely into space, the comet forms two tails: one made of dust while the other made of ionized molecules and radicals. When they get near the Sun, they heat up and begin to release gases (we call this process outgassing), forming a huge glowing atmosphere around the comet nucleus. Furthermore, there are thousands of other planetary systems in the universe.įigure 1: Types of Planets under the Geophysical Planet Definition CometsĬomets are celestial objects that have a nucleus of ice and dust. There are also the dwarf planets: Pluto, Eris, Haumea, Makemake, and Ceres. There are eight planets in the solar system: Mercury, Venus, Earth, and Mars, Jupiter, Saturn, Uranus, and Neptune. Planets are the celestial bodies that move in elliptical orbits around a star. In addition, stars have a great gravitational attraction. Moreover, they are gigantic in size, but we see them as tiny points because they are very far from us. Stars are natural luminous bodies visible in the sky. We can classify these celestial bodies into several categories as below. Since some of these objects are far away, we cannot see them with the naked eye, but we can study them using telescopes. Some of these objects are visible in the night sky. They are a part of the universe and are far away from us. – Comparison of Key Differences Key TermsĬelestial Bodies, Heavenly Bodies, Astronomical Bodies What are Celestial BodiesĬelestial bodies are natural objects in space, such as the Sun, planets, and stars. Difference Between Between Celestial and Heavenly Bodies Similarities Between Celestial and Heavenly BodiesĤ. Sun, moon, and planets in our solar system are some examples of these bodies. The terms celestial bodies, heavenly bodies, and astronomical bodies all refer to natural bodies outside of the earth’s atmosphere. Both these words refer to astronomical bodies, which are the natural bodies outside of the earth’s atmosphere. ![]()
