They are formed in massive gas clouds called 'Extreme Gas Giants' also called "egg's" - there is some controversy about this theory but it is fairly well accepted in the scientific community - hope this helps
Stars are formed in a nebula.
An object moving in space is typically referred to as a celestial body or celestial object. This can include planets, stars, asteroids, comets, moons, and other astronomical entities.
A brown dwarf.
The celestial object that appears to move backwards among the stars is a planet in retrograde motion. This happens when a faster-moving planet "laps" a slower-moving outer planet from the viewpoint of Earth, causing it to look like it is moving backwards relative to the fixed stars in the sky.
The 'stars' are any celestial object that reflects the light from the sun... This can be something as small as a man-made satellite - or as large as a whole galaxy !
A celestial body is any physical body beyond the earth's atmosphere.
No. A celestial object is an object in outer space, such as a planet, star, meteor or comet. Clouds are not in outer space, therefore they are not a celestial object.
There is no celestial object at that distance.
The inside of a planetarium is a sphere with the stars and planets projected on to it. The celestial sphere is an infinite sphere that we imagine has the stars and planets on it. On the celestial sphere only an object's direction matters and its distance is ignored. A viewer at the centre of the planetarium sees stars and planets as they appear in the sky, but viewers in all the seats see approximately the right view.
A celestial object composed primarily of gas, dust, hydrogen, and helium is typically referred to as a "nebula." Nebulae are often the birthplaces of stars and can also be remnants of dead or dying stars. They are characterized by their colorful appearances and vast sizes, containing the raw materials for star formation.
Astral navigation. By using a sextant (instrument used to measure the altitude of a celestial object) a clock and logarithms you can work out your position on the earth's surface hence 'sailing by the stars'
Stars and constellations serve as celestial landmarks by providing a fixed reference point in the night sky, allowing observers to navigate and locate other celestial objects. The patterns formed by constellations help in identifying the positions of stars, which can be used as guides to find nearby celestial bodies. Additionally, the brightness and distinctiveness of certain stars, like Polaris in the Northern Hemisphere, make them useful for orientation and navigation. By learning the relationships and positions of these celestial landmarks, stargazers can effectively map out the night sky.
