Question 1

Orbit

Answer 1

An orbit is a regular, repeating path that one object in space takes around another one. An object in an orbit is called a satellite. A satellite can be natural, like Earth or the moon. Many planets have moons that orbit them

Question 2

Solar System

Answer 2

DescriptionThe Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies

Question 3

Galaxy

Answer 3

A galaxy is a gravitationally bound system of stars, stellar remnants, interstellar gas, dust, and dark matter. The word galaxy is derived from the Greek galaxias, literally “milky”, a reference to the Milky Way.

Question 4

Universe

Answer 4

DescriptionThe Universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.

Question 5

Satellite

Answer 5

DescriptionIn the context of spaceflight, a satellite is an object that has been intentionally placed into orbit. These objects are called artificial satellites to distinguish them from natural satellites such as Earth’s Moon. On 4 October 1957 the Soviet Union launched the world’s first artificial satellite, Sputnik 1.

Question 6

Impact Crater

Answer 6

the partially shaded outer region of the shadow cast by an opaque object.

Question 16

Astronomical Unit (AU)

Answer 16

DescriptionThe astronomical unit is a unit of length, roughly the distance from Earth to the Sun and equal to about 150 million kilometres. However, that distance varies as Earth orbits the Sun, from a maximum to a minimum and back again once a year.

Question 17

Ellipse

Answer 17

a regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant, or resulting when a cone is cut by an oblique plane which does not intersect the base

Question 18

Terrestrial Planet

Answer 18

Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars. The terms “terrestrial planet” and “telluric planet” are derived from Latin words for Earth (Terra and Tellus), as these planets are, in terms of structure, Earth-like.

Question 19

Gas Giant

Answer 19

a large planet of relatively low density consisting predominantly of hydrogen and helium, such as Jupiter, Saturn, Uranus, or Neptune.

Question 20

Asteroid

Answer 20

Asteroids are minor planets, especially of the inner Solar System. Larger asteroids have also been called planetoids.

Question 21

Comet

Answer 21

DescriptionA comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail.

Question 22

Meteor

Answer 22

DescriptionA meteoroid is a small rocky or metallic body in outer space. Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects. Objects smaller than this are classified as micrometeoroids or space dust.

Question 23

Meteorite

Answer 23

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 24

Geocentric

Answer 24

having or representing the earth as the center, as in former astronomical systems.

Question 25

Heliocentric

Answer 25

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

Question 26

Gravity

Answer 26

Gravity is the force that attracts two bodies toward each other, the force that causes apples to fall toward the ground and the planets to orbit the sun. The more massive an object is, the stronger its gravitational pull.

Question 30

Gibbous Moon

Answer 30

Just after the First Quarter Moon, when we can see exactly half of the face of the Moon illuminated, the intermediate phase called Waxing Gibbous Moon starts. … Gibbous refers to the shape, which is less than the full circle of a Full Moon, but larger than the semicircle shape of the Moon at Third Quarter.

Question 31

Crescent Moon

Answer 31

Noun. crescent moon (plural crescent moons) The Moon as it appears early in its first quarter or late in its last quarter, when only a small arc-shaped section of the visible portion is illuminated by the Sun

Question 32

Full Moon

Answer 32

DescriptionThe full moon is the lunar phase when the Moon appears fully illuminated from Earth’s perspective. This occurs when Earth is located between the Sun and the Moon. This means that the lunar hemisphere facing Earth – the near side – is completely sunlit and appears as a circular disk

Question 33

New Moon

Answer 33

DescriptionIn astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude. At this phase, the lunar disk is not visible to the unaided eye, except when silhouetted during a solar eclipse. Daylight outshines the earthlight that dimly illuminates the new moon.

Question 34

Quarter Moon

Answer 34

A quarter moon occurs when we see the Moon half illuminated by the Sun, and half enshrouded in darkness. Since the illuminated side points towards the Sun, it tells astronomers that the Moon and the Sun are separated by 90-degrees from our perspective here on

Question 35

Perihelion

Answer 35

the point in the orbit of a planet, asteroid, or comet at which it is closest to the sun.

Question 36

Aphelion

Answer 36

DescriptionApsis denotes either of the two extreme points in the orbit of a planetary body about its primary body. The plural term, “apsides,” usually implies both apsis points; apsides can also refer to the distance of the extreme range of an object orbiting a host body.
