Meteoroids are distinguished as objects significantly smaller than asteroids, ranging in size from grains to objects ...
A. Ablation – the process of a meteorite losing mass during the passage through the atmosphere. Acapulcoite – a group of primitive achondrites. Accretion – the process in which matter of the protoplanetary disk coalesces to form planetesimals. Achondrite – a differentiated meteorite (meaning without chondrules ).
Meteor shower. A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories.
Traditionally, small bodies orbiting the Sun were classified as comets, asteroids, or meteoroids, with anything smaller than one meter across being called a meteoroid. The term asteroid never had a formal definition, with the broader term small Solar System bodies being preferred by the International Astronomical Union (IAU).
Meteorite. The 60- tonne, 2.7 m-long (8.9 ft) Hoba meteorite in Namibia is the largest known intact meteorite. [1] A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the ...
The meteoroid is at the bright head of the trail, and the recombination glow of the ionised mesosphere is still visible for about 0.7 seconds in the tail.

Leonids. The Leonids ( / ˈliːənɪdz / LEE-ə-nidz) are a prolific annual meteor shower associated with the comet Tempel–Tuttle, and are also known for their spectacular meteor storms that occur about every 33 years. [5] The Leonids get their name from the location of their radiant in the constellation Leo: the meteors appear to radiate ...
Definitions.
