dark bands around certain planets, notably Jupiter
NASA spacecraft en route to Saturn, carrying the Huygens probe to it's moon Titan
the effect of an object’s apparent swerving as seen from a rotating body’s surface, as the object moves north or south of a body’s equator. Though the object is proceeding straight, following Newton’s laws of motion, its apparent swerving is attributed to a fictitious force, which isn’t really a force at all
Coriolis force
The four brightest satellites of Jupiter
Galilean satellites
NASA spacecraft in orbit around Jupiter that sent a probe into Jupiter’s clouds in 1995
Jupiter, Saturn, Uranus, Neptune; or even larger extrasolar planets; same as Jovian planets
Gas Giant Planets
Using the gravity of one celestial body to change a spacecraft’s energy
gravity assist
A giant circulating region on Jupiter
Giant Red Spot
with equatorial diameter greater than the polar diameter
having the diameter along the axis of rotation longer than the equatorial diameter
belts of charged particles surrounding planets
Radiation belts
Giant lightning
Bright bands in the clouds of a planet, notably Jupiter's
scientist, born Italian and later director of the Paris Obs
the major division in the rings of Saturn
Cassini's division
the sphere for each mass inside of which blobs of gas cannot agglomerate by gravitational interaction without being torn apart by tidal forces; normally about 2 1/2 times the radius of a planet
Roche Limit
an ultraviolet emission on the sunlit side of Uranus thought to result from sunlight splitting hydrogen molecules into protons and electrons, with the electrons accelerated perhaps by the magnetic field; Uranus
a giant circulating region on Neptune seen by Voyager 2 on Neptune; it has since disappeared
Great Dark Spot
the outer limit of the Sun's influence on space; where the solar wind becomes weaker then interstellar matter; neptune
a reservoir of perhaps hundreds of thousands of solar system objects, each hundreds of kilometers in diameter, orbiting the Sun outside the orbit of Neptune. It is the source of short period comets
Kuiper Belt
a method obtaining higher resolution of an image by analysis of a rapid series of exposures that freeze atmosphere blurring
speckle interferometry
a sloar-system object, with 2060 chiron as the forst example, intermediate b/w comets and icy planets or satellites and orbiting the sun b/w the orbits of Jupiter and Neptune
of a comet, the region surrounding the head
a type of object orbiting the sun, often in a very elongated orbit, that when relatively near to the sun shows a coma and may show a tail
realatively simple molecules in comets resulting from the breakup of more complex molecules
daughter molecules
a theory explaining comets as amalgams of ices, dust, adn rocks
dirty snowball
the dust left behind a comet, reflecting sunlight
Dust tail
the puffs of ionized gas trailing a comet
gas tail
of a comet, the nucleus and coma together
an object in the Kuiper belt; many comets and perhaps even the planet pluto are examples
kuiper belt object
an occultation by the moon
lunar occulation by the moon
the chunks of matter, no more than a few km across, at the center of the head of a comet
the hiding of one astornomical body by another
the trillions of incipient comets surrounding the solar system in a 50,000 AU sphere
Oort comet cloud
the more complex molecules form which observed molecules were formed, as in a comet for which we see simple molecules the persumably came from a parent that contained more atoms
parent molecules
gas and dust left behind as a comet orbits sufficiently close to the sun, illuminated by sunlight
a type of stony meteorite without chondrules
a group of asteroids with semimajor axes greater then earth's and perihelion distances b/w 1.017 AU and 1.3 AU; about half across the earth's orbit
amor asteroids
a group of asteroids, with semimajor axes greater then Earth's and perihelion distances less than 1.017 AU
Apollo asteroids
A "minor planet", a non-luminous chunk of rock smaller then planet-size but larger than a meteoroid, in orbit around a star
a region of the solar system, b/w the orbits of Mars and Jupiter, in which most of the asteroids orbit
asteroid belt
a group of asteroids with semimajor axes smaller than 1 AU and aphelion distances greater than 0.983 AU
Aten asteroids
a very bright meteor from which a sound is heard
containing a lot of carbon
A type of carbon-rich stony meteor, thought to be primitive material from the early era of the solar system. Chondrules are embedded in carbon-rich minerals.
carbonaceous chondrites
A type of stony meteorite that contains small crystalline spherical particles called chondrules.
an exceptionally bright meteor
iron meteorites
a track of light in the sky from rick or dust burning up as it fall's through the earth's atmosphere
The occurrence at yearly intervals of meteors at a higher-than-average rate as the Earth goes through a comet's orbit and the dust left behind by that comet.
meteor shower
An interplanetary chunk of rock after it impacts on a planet or moon, especially on the Earth.
An interplanetary chunk of rock smaller than an asteroid.
A tiny meteorite. The micrometeorites that hit the Earth's surface are sufficiently slowed down that they can reach the ground without being vaporized.
minor planets
A comet or asteroid whose orbit is sufficiently close to Earth's that a collision is possible or even likely in the long term. See Amor asteroids, Apollo asteroids.
near-earth objects
the point in the sky from which all the meteors in a meteor shower appear to be coming
shooting stars
a time of many meteors from a common cause
not regularly
a meteor not associated with a shower
sporadic meteor
a stony type of meteorite, including the chondrites
A type of meteorite including properties of both stoney meteorites (that is, silicates) and iron-nickel meteorites. Pallasites are the dominant example.
stony-iron meteorite
Small glassy objects found scattered around the southern part of the southern hemisphere of the Earth.
One of the sub-planetary objects in the Kuiper belt; it was proposed but not accepted that Pluto should be considered as one.
Trans-Neptunian Object (TNO)
A group of asteroids that precede or follow Jupiter in its orbit by 60°.
Trojan asteroids
