Question

To locate Sirius with the help of Orion, an imaginary line is to be drawn towards _________.
A. South
B. North
C. West
D. East

Answer 1

Hint: Orion is a group of stars which can be spotted in the sky. An imaginary line passing through the three middle stars of Orion when drawn towards the east, will lead to a bright star called Sirius.

Complete step by step answer:
Three bright stars are called the Alnitak, Alnilam and Mintaka from Orion's belt. Orion can easily be located by finding a group of three stars which forms Orion's belt. The brightest star in the sky is called Sirius. If we draw an imaginary line passing through the three stars that form the Orion’s belt, in a downward direction and to the left, we will reach a bright star which will be Sirius.

So, the correct answer is “Option D”.

Additional Information:
According to Greek mythology, the constellation Orion is named after the hunter Orion. The dog of the hunter was called Sirius. Hence, Sirius is sometimes referred to as the ‘Dog star’.

Note:
Orion is a constellation, therefore, it consists of many stars. Two stars called Betelgeuse and Rigel are the brightest stars of Orion. But it is difficult to locate these stars in the sky. Orion can easily and accurately be located in the night sky by three stars in a short straight line. We must remember that Sirius is a single star and not a part of the Orion constellation. We only use Orion to locate Sirius.
