Write short notes under météorites and terrestrial planets?

Météorites:
- Météorites are fragments of asteroids or other celestial bodies that have survived their journey through Earth's atmosphere and landed on the surface.
- They provide valuable information about the composition and history of the early solar system.
- Météorites can be classified into three main types: stony, iron, and stony-iron.
- Scientists study météorites to learn more about the formation and evolution of planets and other celestial bodies.

Terrestrial planets:
- Terrestrial planets are rocky planets that are similar in composition to Earth.
- The four terrestrial planets in our solar system are Mercury, Venus, Earth, and Mars.
- These planets have solid surfaces, dense metallic cores, and relatively thin atmospheres.
- Terrestrial planets are typically located closer to the sun than gas giants like Jupiter and Saturn.
- Earth is the only terrestrial planet known to support life.

Météorites

- Small pieces of extraterrestrial material that have fallen to Earth.
- Originate from asteroids, comets, or the Moon.
- Classified into three main types:
- Stony: composed of silicate minerals
- Iron: composed of iron and nickel
- Stony-iron: a mixture of stony and iron materials

Terrestrial Planets

- Inner planets that are rocky, dense, and have little gas.
- Four terrestrial planets in our solar system:
- Mercury
- Venus
- Earth
- Mars
- Characterized by:
- Solid surfaces
- Metal cores
- Low atmospheric pressure
- Minimal to no magnetic fields
