Answer 1

Answer:

Stars-

A star is an astronomical object consisting of a luminous spheroid of plasma held together by its own gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but due to their immense distance from Earth they appear as fixed points of light in the sky.

Constellation-

A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived outline or pattern, typically representing an animal, mythological person or creature, or an inanimate object. The origins of the earliest constellations likely go back to prehistory.

Pole-

The North Pole lies in the Arctic Ocean while the South Pole is in Antarctica. ... Relative to Earth's surface, the geographic poles move by a few metres over periods of a few years.
