Index Earth-grazing fireball

An Earth-grazing fireball (or Earth grazer) is a fireball, a very bright meteor that enters Earth’s atmosphere and leaves again.[1]

Apollo asteroid

The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s.

See Earth-grazing fireball and Apollo asteroid

Aten asteroid

The Aten asteroids are a dynamical group of asteroids whose orbits bring them into proximity with Earth.

See Earth-grazing fireball and Aten asteroid

Atmosphere of Earth

The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by Earth's gravity.

See Earth-grazing fireball and Atmosphere of Earth

Atmospheric entry

Atmospheric entry (sometimes listed as Vimpact or Ventry) is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite.

See Earth-grazing fireball and Atmospheric entry

Bolide

A bolide is normally taken to mean an exceptionally bright meteor, but the term is subject to more than one definition, according to context. Earth-grazing fireball and bolide are atmospheric entry and meteoroids.

See Earth-grazing fireball and Bolide

Christmas Eve

Christmas Eve is the evening or entire day before Christmas Day, the festival commemorating the birth of Jesus.

See Earth-grazing fireball and Christmas Eve

Desert Fireball Network

The Desert Fireball Network (DFN) is a network of cameras in Australia.

See Earth-grazing fireball and Desert Fireball Network

Earth

Earth is the third planet from the Sun and the only astronomical object known to harbor life.

Earth-grazing meteoroid of 13 October 1990

On 13 October 1990, meteoroid EN131090, with an estimated mass of 44 kg, entered the Earth's atmosphere above Czechoslovakia and Poland and, after a few seconds, returned to space. Earth-grazing fireball and Earth-grazing meteoroid of 13 October 1990 are Earth-grazing fireballs and meteoroids.

European Fireball Network

European Fireball Network is an international astronomy organization based in Central Europe (Germany and Czech Republic).

Exosphere

The exosphere (ἔξω éxō "outside, external, beyond", σφαῖρα sphaĩra "sphere") is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collision-less.

See Earth-grazing fireball and Exosphere

Leonids

The Leonids 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.

See Earth-grazing fireball and Leonids

Mesosphere

The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere.

See Earth-grazing fireball and Mesosphere

Meteor procession

A meteor procession occurs when an Earth-grazing meteor breaks apart, and the fragments travel across the sky in the same path. Earth-grazing fireball and meteor procession are meteoroids.

See Earth-grazing fireball and Meteor procession

Meteorite

A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon.

See Earth-grazing fireball and Meteorite

Meteoroid

A meteoroid is a small rocky or metallic body in outer space. Earth-grazing fireball and meteoroid are meteoroids.

See Earth-grazing fireball and Meteoroid

Natural satellite

A natural satellite is, in the most common usage, an astronomical body that orbits a planet, dwarf planet, or small Solar System body (or sometimes another natural satellite).

See Earth-grazing fireball and Natural satellite

Orbit

In celestial mechanics, an orbit (also known as orbital revolution) is the curved trajectory of an object such as the trajectory of a planet around a star, or of a natural satellite around a planet, or of an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point.

See Earth-grazing fireball and Orbit

Stratosphere

The stratosphere is the second-lowest layer of the atmosphere of Earth, located above the troposphere and below the mesosphere.

See Earth-grazing fireball and Stratosphere

Thermopause

The thermopause is the atmospheric boundary of Earth's energy system, located at the top of the thermosphere.

See Earth-grazing fireball and Thermopause

Thermosphere

The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere.

See Earth-grazing fireball and Thermosphere

1860 Great Meteor

The 1860 Great Meteor procession occurred on July 20, 1860. Earth-grazing fireball and 1860 Great Meteor are Earth-grazing fireballs and meteoroids.

See Earth-grazing fireball and 1860 Great Meteor

1913 Great Meteor Procession

On February 9, 1913, a significant meteoric phenomenon was reported from locations across Canada, the northeastern United States, Bermuda, and from many ships at sea as far south as Brazil, giving a total recorded ground track of over, and becoming known as the Great Meteor Procession of 1913. Earth-grazing fireball and 1913 Great Meteor Procession are meteoroids.

See Earth-grazing fireball and 1913 Great Meteor Procession

1972 Great Daylight Fireball

The Great Daylight Fireball (also known as the Grand Teton Meteor) was an Earth-grazing fireball that passed within of Earth's surface at 20:29 UTC on August 10, 1972. Earth-grazing fireball and 1972 Great Daylight Fireball are Earth-grazing fireballs and meteoroids.
