Question Answer
Term: Star Definition: Celestial space that has great size and emit light as a source of light. Example: The Sun, it is the closest star to Earth.
Term: Planet Definition: Celestial bodies that surround the star as the centre of the solar system. The planet can not produce its own light but can reflect light.
Term: Satellite Definition: Objects that orbit around the planet that has its own circulation. Example: The Moon is the Earth's natural satellite.
Term: Comet Definition: Celestial bodies that orbit the sun. Comets have orbits own orbit whose shape is oval. Commonly referred to as a comet comet because of its bright glowing gas and dust tail is very long.
Term: Moon Definition: The natural satellite of the earth, visible (chiefly at night) by reflected light from the sun.
Term: Galaxy Definition: A system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.
Term: Quasar Definition: A massive and extremely remote celestial object, emitting exceptionally large amounts of energy, which typically has a starlike image in a telescope. It has been suggested that quasars contain massive black holes and may represent a stage in the evolution of some galaxies.
Term: Pulsar Definition: A neutron star that emits rapid and periodic pulses of radiation. A neutron star is an extremely compact or dense ball of neutrons created from the central core of a star that collapsed under gravity during a supernova explosion.
Term: Black hole Definition: It is extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this interval a supernova can radiate as much energy as the Sun is expected to emit over its entire life span.
