Meteors and Meteorites - NASA Science
Meteors, and meteorites are often called “shooting stars” - bright lights streaking across the sky. We call the same objects by different names, depending on where they are located.
Meteors & Meteorites Facts - Science@NASA
Scientists can tell where meteorites originate based on several lines of evidence. They can use photographic observations of meteorite falls to calculate orbits and project their paths back to the asteroid belt. They can also compare compositional properties of meteorites to the different classes of asteroids.

Meteors and Meteorites: Exploration - Science@NASA
An experiment on the International Space Station called Meteor Composition Determination studied the chemical composition of meteors entering Earth’s atmosphere. The Meteor investigation took high-resolution video and images of the atmosphere and used a software program to search for bright spots.
Asteroids, Comets & Meteors Facts - Science@NASA
The discovery supports the theory that some of life's ingredients formed in space and were delivered to Earth long ago by meteorite and comet impacts. Like forensic detectives, scientists follow clues about what happened when the solar system was young to …
Apophis - NASA Science
There are no high-resolution images of the surface of asteroid Apophis, but it is likely similar to surfaces of other stony-type asteroids like Itokawa, the first asteroid from which samples were captured and brought to Earth for analysis.
Quadrantids - NASA Science
2023年12月26日 · The Quadrantids, which peak during early-January each year, are considered to be one of the best annual meteor showers. Most meteor showers have a two-day peak, which makes catching sight of these other meteors much more possible. The Quadrantids peak, on the other hand, is much shorter – only a few hours.
Geminids - NASA Science
2023年12月24日 · Unlike most meteor showers which originate from comets, the Geminids originate from an asteroid: 3200 Phaethon. Asteroid 3200 Phaethon takes 1.4 years to orbit the Sun once. It is possible that Phaethon is a "dead comet" or a new kind of object being discussed by astronomers called a "rock comet."
Orionids - NASA Science
2023年11月22日 · Fast meteors can also sometimes become fireballs: Look for prolonged explosions of light when viewing the Orionid meteor shower. The Orionids are also framed by some of the brightest stars in the night sky, which lend a …
Leonids - NASA Science
A meteor storm versus a shower is defined as having at least 1,000 meteors per hour. Viewers in 1966 experienced a spectacular Leonid storm: thousands of meteors per minute fell through Earth's atmosphere during a 15-minute period.
