    Have you got interest in amateur astronomy?

    Amateur Astronomy is a great hobby. It is also a great learning opportunity about planets, constellations, galaxies, movement of planets across the constellations, shifting of constellations in the night sky etc.
    On a clear night sky away from city lights one can simply glance up and can try to visualise the various imaginary shapes made by the group of stars and these shapes are the constellations. As stars are very far from us these shapes remain same and due to the Earth's rotation around its axis from West to East the constellations appear to move from East to West.
    Comparatively, the planets of our solar system are very near to us and they also appear in the night sky moving across these constellations. The simple way to distinguish between stars and planets is that stars will twinkle but planets will look like light dots.
    A lot of observations can be made by amateur astronomer with the naked eye but if he has a telescope it will give more deep knowledge about the sky and its content above us.
    As Earth revolves around Sun and takes one complete round in one year so after one year the observer will see the same pattern of constellations in the sky as he had seen a year back.
    It is amazing that our ancestors in Indian peninsula made so many observations about the night sky and had even named the constellations and stars in a particular way and even did find their distances and other things using their simple mathematical methods based on yearly observations.
    Have you also got any interest in amateur astronomy? Please share your views about it.

    During my childhood, my grandfather used to show me various stars, constellations etc.I remember very much one such constellation called 'Sapta Rushi Mandalam'. This constellation used to have seven stars and each one is a saint and they are seven saints together. He used to show me some stars and used to tell their names. Star by name Arundathi also he used to show me. He was having a lot of knowledge about this amateur astronomy. Unfortunately, I could not learn much from him. In midnight he used to go out and measure the size of the shadow and used to tell the time also at that moment and it used to tally exactly with the time in our wall clock.

    Yes, Saptarshi is a pattern of seven stars in a question mark shape. They rotate around the pole star (as per Indian astronomy pole star is known as Dhruv). Pole star remains at its place because it is falling on the axis of Earth around which Earth rotates and we feel day and night.
    Knowledge is power.

    Now also I can identify that dhruva nakshatra and arundhathi also. What is the star that is very near to the moon on that day and what will be the name of that star also I have learned from my grandfather and I am trying to teach the same to my granddaughters.

    In our Indian Astronomy each star in the Saptarshi is given a name of the famous saint. One of them is Vasishtha. There is one faint star very near to it which was named by our ancestors as Arundhati (wife of sage Vasishtha).
