Heavenly matter landing on the earth’s surface is known as?
1. Meteorite
2. Shooting star
3. UFO
4. Galaxy

Answer 1

Correct Answer - Option 1 : Meteorite

The correct answer is Meteorite.

• Meteo rite
  • A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.
  • Heavenly matter landing on the earth’s surface is known as Meteorite.
  • A meteor is simply an asteroid that attempts to land on Earth but is vaporized by the Earth’s atmosphere.
    • The resistance on the rock due to the Earth’s atmosphere causes its temperature to rise.
    • We sometimes see the glowing hot air created by these burning meteors and dub them “shooting stars”.
    • Meteor showers occur when the Earth passes by many meteors at once.
    • For example, if chunks of a comet melt off as it passes close to the Sun, this debris can be left behind to later dazzle us, Earthlings, with a meteor shower.

• Galaxy
  • A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter.
  • The word galaxy is derived from the Greek galaxies, literally "milky", a reference to the Milky Way.​
• Shooting star
  • ​The Shooting Star looks exactly the same as the Inverted hammer, but instead of being found in a downtrend, it is found in an uptrend and thus has different implications. ​
• What is an Asteroid?
  • Asteroids are rocky objects smaller than planets that are leftover from the formation of our solar system.
  • When the cloud of gas and dust collapsed to form our Sun, much of the remaining material went into forming the rocky terrestrial and gas giant planets orbiting our star.
  • Smaller dust fragments that never made their way into planets are left behind as asteroids.
• What is a Comet?
  • Comets are also composed of material left over from the formation of our solar system and formed around the same time as asteroids.
  • However, asteroids formed toward the inner regions of our solar system where temperatures were hotter, and thus only rock or metal could remain solid without melting.
