SOLAR SYSTEM

Detailed explanation-1: -Asteroids and meteoroids are small rocky objects, much smaller than planets, that orbit the sun. If it is larger than 1 meter in diameter, then it is an asteroid; if it is 2 millimeters to 1 meter in size, it is a meteoroid. If it is smaller than 2 mm, it is a micrometeoroid.

Detailed explanation-2: -A meteoroid is a natural fragment of rock less than 1 km (. 6 mi) across that orbits the Sun. A meteor is the streak of light caused when a meteoroid enters Earth’s atmosphere.

Detailed explanation-3: -The majority of visible meteors are caused by particles ranging in size from about that of a small pebble down to a grain of sand, and generally weigh less than 1-2 grams.

Detailed explanation-4: -Space debris smaller than an asteroid are called meteoroids. A meteoroid is a piece of interplanetary matter that is smaller than an asteroid and frequently are only millimeters in size. Most meteoroids that enter the Earth’s atmosphere are so small that they vaporize completely and never reach the planet’s surface.

Detailed explanation-5: -NASA scientists say it would take an asteroid 60 miles (96 kilometers) wide to totally wipe out life on Earth.
