Answer:
# Stars and Planets
•°Stars Planets
(1)Stars are incredibly hot having high temperatures to them. Planets, on the other hand, have relatively low temperatures.
(1)They are objects that produce their own light and do not rely on an external source for the production of light Planets are incapable of producing their own light.
(2)Stars have a unique effect of twinkling in the sky. Planets do not exhibit the twinkling effect unlike stars
(2)The stars change their position, but can be seen only after a long time due to substantial distance. Planets in orbits on their own axis change their positions constantly.
(3)Stars consist of matters like Hydrogen, Helium, and other light elements.
(3)Planets, on the other hand, contains solids, liquids, gases, or a combination thereon.

#meteor and meteorite
•°Meteor & Meteorite
#Definition
1. lf a meteoroid enters the Earth’s atmosphere and vaporizes, it becomes a meteor, which is often termed as a shooting star.
1. A fragment of rock or iron originates from outer space, which is a meteoroid or asteroid, which survives passage through the atmosphere as a meteor to impact the surface of the Earth is termed as a meteorite.
#Size
2. They are usually millimeter-sized or smaller.
2. Their size can range from about a fraction of a gram to 100 kilograms
#Types
3. There are different types of meteors: Earth grazers, Fireballs, Bolides
3. Meteorites have traditionally been divided into three broad categories Stony meteorites, iron meteorites, and stony-iron meteorites
#Origin
4. Meteors are considered to be part of the Solar System .
4. Meteorite originates from outer space
#Composition
5. Meteors are burning rocks
5. Meteorites contain a combination of metal, magnetic elements, and nickel.

Planet and Satellite
•°Planet & Satellite
(1)As per modern definitions, any astronomical body orbiting a star can be classified as a planet (1)Satellites both natural and artificial, orbit relatively close to planets or any other celestial body with a relatively bigger mass.
(2)The axial tilt of the planet is at an angle to the plane of their star’s equators. This causes the amount of light received in the hemisphere to vary throughout its span of rotation
(2)Satellites orbiting relatively close to the planets on uninclined circular orbits are thought to have been formed out of a collision between two astronomical bodies
(3)The term ‘planet’ is derived from the Greek word “planan” meaning “to wander”.
(3)The term ‘satellite’ is derived from the Latin word ‘satelles’ meaning ‘to follow” or “to attend to”
(4)Planets rotate around the invisible axes through their centers. Most of the planets in the solar system orbit the sun
(4)Natural Satellites in the Solar System are tidally locked to their respective planet, meaning that the same side of the natural satellite always faces its planet.
(5)The huge size of the planet is responsible for the domination of the gravitational force over the electromagnetic force. This results in hydrostatic equilibrium.
(5)The mass of satellites will always be smaller from that of planets and they will be reliant upon the planet’s gravity for it to orbit.
(6)Examples of planets are Earth, Jupiter, Saturn, etc.
(6)Examples of satellites are the Moon orbiting the Earth, Titan orbiting Saturn and Europa orbiting Jupiter.
