Question 3

Universe

Answer 3

Space and all the matter and energy in it.

Question 4

Satellite

Answer 4

An object that orbits a more massive object.

Question 5

Impact crater

Answer 5

A round pit left behind on the surface of a planet or other body in space that a smaller object strikes the surface.

Question 6

Axis of rotation

Answer 6

An imaginary line about which a turning body such as earth rotation.

Question 7

Revolution

Answer 7

The motion of one body around another such as earth and it orbit around the sun the time it takes and object to go around once.

Question 8

Season

Answer 8

One part of a pattern of temperature change and another weather trends over the course of a year.

Question 9

Equinox

Answer 9

In an orbit a position and time in which sunshines equally on the northern hemisphere and the Southern Hemisphere a time of year when day light and darkness are nearly equally on earth.

Question 10

Solstice

Answer 10

In an orbit a position and time during which one hemisphere gets it’s maximum area of day light wile the other hemisphere gets it’s maximum amount.

Question 11

Mare

Answer 11

A mare is an adult female horse.

Question 12

Eclipse

Answer 12

An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer.

Question 13

Umbra

Answer 13

The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object. For a point source only the umbra is cast.

Question 14

Penumbra

Answer 14

the partial or imperfect shadow outside the complete shadow of an opaque body, as a planet, where the light from the source of illumination is only partly cut off.

Question 15

Astronomical unit

Answer 15

The astronomical unit is a unit of length, roughly the distance from Earth to the Sun. However, that distance varies as Earth orbits the Sun, from a maximum to a minimum and back again once a year.

Question 16

Ellipse

Answer 16

In mathematics, an ellipse is a curve on a plane that surrounds two focal points such that the sum of the distances to the two focal points is constant for every point on the curve.

Question 17

Terrestrial planet

Answer 17

Within the Solar System, the terrestrial planets are the inner planets closest to the Sun. Mercury, Venus, Earth, and Mars. The terms “terrestrial planet” and telluric planets are derived from Latin words for Earth.

Question 18

Gas giant

Answer 18

A gas giant is a giant planet composed mainly of hydrogen and helium. Jupiter and Saturn are the Solar System’s gas giants.

Question 19

Comet meteor

Answer 19

A small particle from an asteroid or comet orbiting the Sun. Meteor: A meteoroid that is observed as it burns up in the Earth’s atmosphere - a shooting star. Meteorite: A meteoroid that survives its passage through the Earth’s atmosphere and impacts the Earth’s surface.

Question 20

Meteorite

Answer 20

A meteorite is a fragment of rock or iron from outer space, usually a meteoroid or asteroid, which survives passage through the atmosphere as a meteor to impact the surface of the Earth. Meteorites are believed to originate in the asteroid belt between the planets of Mars and Jupiter.

Question 21

Geocentric

Answer 21

In astronomy, the geocentric model (also known as geocentrism, or the Ptolemaic system) is a description of the cosmos where Earth is at the orbital center of all celestial bodies.

Question 22

Heliocentric

Answer 22

having or representing the sun as the center, as in the accepted astronomical model of the solar system.

Question 23

Gravity

Answer 23

Gravity or gravitation is a natural phenomenon that brings towards one another like stars planets and even light by sub atomic particles.

Question 24

Tide

Answer 24

Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth.

Question 25

Waxing

Answer 25

the moon at any time after new moon and before full moon, so called because its illuminated area is increasing. Compare waning moon. Origin of waxing moon Expand.

Question 26

Waning

Answer 26

The word crescent refers to the phases where the moon is less than half illuminated. The word gibbous refers to phases where the moon is more than half illuminated. Waxing essentially means “growing” or expanding in illumination, and waning means “shrinking” or decreasing in illumination.

Question 27

Gibbous moon

Answer 27

The word crescent refers to the phases where the moon is less than half illuminated. The word gibbous refers to phases where the moon is more than half illuminated. Waxing essentially means “growing” or expanding in illumination, and waning means “shrinking” or decreasing in illumination.

Question 28

Crescent moon

Answer 28

A crescent moon is part way between a half moon and a new moon, or between a new moon and a half moon.A full moon appears as an entire circle in the sky. The full moon is given different names, depending on when it appears.

Question 29

Full moon

Answer 29

the moon when the whole of its disk is illuminated, occurring when in opposition to the sun.

Question 30

New moon

Answer 30

the phase of the moon when it is in conjunction with the sun and invisible from earth, or shortly thereafter when it appears as a slender crescent.

Question 31

Quarter moon

Answer 31

Third Quarter. The moon is one-half illuminated by the sun. Occurs when the moon’s illumination is decreasing, Waning Crescent. The moon is less than one-half illuminated by the sun but less than one quarter illuminated.

Question 32

Orbit

Answer 32

The path of an object in space as it moves around another object due to gravity.
