Measures of Astronomical Distances • Let’s view the Universe in terms of kilometres – The size of the observable universe is roughly 130‚000‚000‚000‚000‚000‚000‚000 km ! - Obviously measuring astronomical distances in km is inconvenient. - We need much BIGGER units of distance: • Some commonly used distance units: 1 ly (light year) = Distance traveled by light in 1 year = 9.46 trillion km 1 AU (astronomical unit) = average distance between the Sun & Earth = 150 million km A unit of distance‚

Furthermore‚ mass varies from planet to planet due to the different gravitational pulls. Time also varies because rotations of planets are different; therefore‚ seconds‚ hours‚ and days are longer or shorter depending on where you are in the solar system. As stated before‚ humans commonly use light years‚ parsecs‚ and the astronomical unit

Kusumapura. The University of Nalanda was in Pataliputra at the time. This university had an astronomical observatory that forces the belief that Aryabhata was the head of the Nalanda University. Aryabhata set up an observatory at the Sun temple in Taregana‚ Bihar (Aryabhata – Indian Mathematician). Aryabhatiya deals with mathematics and astronomy. That consists of an introduction containing astronomical tables and Aryabhata’s system of phonemic number notation. This work consists of three sections:
