What Are Celestial Objects Exactly
The universe is loaded with celestial objects. Though empty space is vast, every now and then there is an asteroid belt, a moon, or a star that breaks the monotonous emptiness. And there are more like objects with strong gravitational pull but does not have land mass. Let us discuss the most basic of all celestial objects.
Star – it was the sign in the heavens to locate Jesus. It is also the celestial body that navigators use. The sun is a good example. People in the past saw shapes, animals, and human images if they connect it and made stories about it. Yes it is the star. And the shapes are called constellations. Our sun, which is a type of a star, is the reason why we are alive. Do not be shocked but stars do not twinkle. The twinkling effect is brought about by atmospheric interference, just like when you get a blurred view of things when the surrounding is stifling hot. There are six major types of stars:
1. Binary stars – these are two stars stuck to each other because of their gravitational pull. They have a common orbit point.
2. Variable stars – when a stars brightness fluctuates, it is a variable star. The color fluctuations from seconds to years, depending on the reason for the fluctuation.
3. Brown dwarfs – is a star that never became a full star. It is a huge ball of gas that is too small for a star but too big for a planet.
4. White dwarf – it is the leftover of a burned out star.
5. Red giants – it is a star that is about to use up all its fuel
6. Main sequence star – it is a full star that has reached the peak of its existence
Planets – are officially any celestial body that orbits any type of star that keeps it in a consistent orbit.
Moon – the most romantic celestial body. It has spawned a lot of poems and songs about romantic trysts and forbidden love. In the past, the moon was actually worshipped and at times dreaded. As a planet is a celestial body that orbits around a star, a moon orbits around a planet. Some planets have multiple moons, as many as twenty one for Uranus. Venus and Mercury though do not have moons. It takes 27 complete days for the Earth’s moon to finish a whole orbit.
Comets and asteroids – are space surplus from planets and other huge celestial bodies. The most famous of these celestial bodies is Halley’s Comet which returns within visible distance to Earth every seventy six years.
