The precession of our planet is majorly influenced by Sun and Moon’s gravitational influence also known as Lunisolar Precession and minorly by other planets in our solar system. Due to this motion, the celestial pole precesses in 26,000 years. This precession causes pole stars to change every 2000 – 4000 years. Before we could understand which stars were the pole stars in the past, we must understand What a Pole Star is? What features distinguish a normal star from a pole star? A pole star is a position in the sky that is always in the polar direction. A North Pole star can be seen in the northern direction and similarly, a south pole star in the southern direction. As most of the older civilizations grew in the northern hemisphere we have much more knowledge and idea about the North Pole star. Still, we have less evidence of which star used to be the north pole star. Over here we tried to figure out the possible north pole star. So we took three considerations.

Mentor : Currently serving as the director of Nehru Planetarium, Mumbai (since December, 2011); Arvind has been interested in Astronomy for most of his life. His first accolade in the field was being a part of the team at the Indian Institute of Astrophysics that became the first in India to discover a new Asteroid. This was in 1988 and the asteroid was named 4130 Ramanujan. The team was awarded Astronomical Society of India Medal for the discovery of an asteroid. On 23rd January 1990, the team discovered another asteroid 17446 Mopaku which was awarded its name after the 3 team members Venkatachala Moorthy, Arvind Paranjpye, and Kamatchiappan Kuppuswamy. Arvind joined the Inter-University of Astronomy and Astrophysics (IUCAA) in 1991 an
