Answer:
In astronomy, a syzygy (/ˈsɪzɪdʒi/; from the Ancient Greek σύζυγος, suzugos, 'yoked together'[2]) is a roughly straight-line configuration of three or more celestial bodies in a gravitational system.[3]
Solar System
If you look at the sky above you, during the night time, you’ll notice that it is full of tiny shining objects. Some of these objects are bright while others are dim. Most of them, seem to be twinkling. The reality is not all of the objects in the sky can be seen with the naked eye. It is our solar system which is full of these objects. So let’s study the solar system in detail.
Celestial Bodies
The sun, the moon, and all the objects, shining in the night sky are known as the Celestial Bodies. This includes every natural object that is located outside the Earth’s atmosphere, such as the Moon, the Sun, an asteroid, planet, or star. The Kuiper belt contains many celestial bodies. Even an asteroid in space is a celestial body.
The Moon
Our planet Earth only has one natural satellite which is the moon. The moon appears to be extremely big to us. This is because it is nearer to our planet in comparison to the other celestial bodies. The moon moves around the earth in about 27 days and 8 hours. On the moon, the atmospheric conditions are not favourable to support life.
The moon always moves in a synchronous rotation with Earth. This means that the same side is always facing the Earth. Every once a month, you’ll see a full moon night. It is known as Poornima. A fortnight later, you’ll not be able to see any moon at all. It is a new moon night also known as new moon night or ‘Amavasya’.
