While gazing up at the night sky, have you wondered how high the sky is? The atmosphere that envelops the earth is divided into different layers. The Troposphere – closest to the earth’s surface extends up to 15 km, the Stratosphere extends from 15 to 45 km, the Mesosphere extends from 45 to 85 km and the final layer, Thermosphere extends up to 500 km. The Exosphere is the outermost layer of the atmosphere which extends almost up to 10,000 km. Beyond this is the seemingly endless expanse of our Universe.

Moon – the nearest celestial body to the earth, is 3,84,400 km away from the earth. Sun – earth’s source of energy, is 1,50,00,00,00,000 km away. The nearest star to the earth, Proxima Centauri – 3,99,00,00,00,00,000 km away.

Space holds a never-ending fascination for scientists and explorers.
