Question

Hunter constellation can be used to locate:
(a) Pole star
(b) Apollo
(c) Sirius
(d) Regal

Answer 1

Hint: Hunter constellation is also known as the Orion constellation.
By using the Hunter constellation, we can find the brightest star of the sky in Canis Major.

Complete step by step solution:
Constellation refers to a group of stars that form a pattern or resemble a picture.

Some examples of constellation are:
The great Hunter, Leo the lion, Taurus the bull.
The great hunter is also known as The Orion.

Orion being the most visible of all other constellations can be used to observe other stars.
It uses its three sparkling belt stars to observe other stars.

On drawing a line through Orion’s belt towards the Rudy star Aldebaran, in Taurus bull constellation. Opposite direction of this line leads to the brightest star in the sky. This star is Sirius.
Sirius is also referred to as Alpha Canis Major.

Sirius is also known as the Dog Star as it belongs to the constellation of Canis Major, the greater dog.

Therefore, Sirius is our correct answer.

Note:
The Orion constellation can be used to spot four bright stars, namely, Betelgeuse and Rigel in Orion – Aldebaran in Taurus the bull and Sirius in Canis Major.
Pole star is the brightest star in the northern hemisphere.

Southern hemisphere, however, does not have a pole star yet; in the near future, it is expected that Sirius might be referred to as the Pole star of the southern hemisphere.

In ancient Greek mythology, the two dogs represented by Canis Major are said to belong to the great hunter Orion.
