Answers
Answer:
the distance of a place north or south of the line that we imagine around the middle of the earth
Explanation:
1) longitude=longitude is the distance on the Earth's surface between a specific point and the prime meridian in Greenwich England,
2) prime meridian= a planet's meridian adopted as the zero of longitude.
3) Equator=The equator of a rotating spheroid is the parallel at which latitude is defined to be 0°.
4) star=a large ball of burning gas in outer space that you see as a small point of light in the sky at night
5) constellation= A group of star that form a patter are known as constellation.
6) latitude=the distance of a place north or south of the line that we imagine around the middle of the earth (the equator)
7) meteorite=a small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.
8) asteroid=a small body moving in the solar system that would become a meteor if it entered the earth's atmosphere.
9) planets=a very large round object in space that moves around the sun or another star
10) Artificial satellite=An artificial satellite is an object that people have made and launched into orbit using rockets.
11) standard meridian=Standard time is the synchronization of clocks within a geographical area to a single standard time, rather than using solar time or a locally chosen meridian (longitude) to establish a local mean time standard.
12) Universe=all existing matter and space considered as a whole; the cosmos. The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.
13) satellite=Satellites are objects that revolve around planets. They form the essential part of the celestial bodies. These may be of natural origin or sent by humans
14) galaxy=the system of stars that contains our sun and its planets, seen as a bright band in the night sky
15) celestial bodies= A natural object which is located outside of Earth's atmosphere, such as the Moon, the Sun, an asteroid, planet, or star.
16)moon=the object that shines in the sky at night and that moves around the earth once every 28 days
Q. 3. Find, which is the closest galaxy to our galaxy, "The Milky way"
ANSWER=Andromeda galaxy, closest large spiral. The Andromeda galaxy is the closest big galaxy to our Milky Way. At 2.5 million light-years, it's the most distant thing you can see with the eye alone.
