There are more than 100 Billion galaxies in the universe.The largest galaxies have nearly 400 Billion stars. There are an estimated 100 Billion stars in the Milky Way in our galaxy. If you tried to count all the stars in just our galaxy at a rate of one star per second, it would take you about 3,000 years.
The Sun around 1.3 Million Earth can fit on it and also it is the largest object in our solar system.It contains roughly 98% of our solar system’s total mass.The surface of the sun is 6.00 degree (11.000 degree F) The interior of the sun is 15,000,000 degree C (27,000,000 degree F)
The Moon is drifting away from the Earth. Every year, the Moon moves 3.8 cm further away from us. Because of this, the Earth is also slowing down. Every century, the Earth’s rotation will be 2 milliseconds slower.In other words, 100 years from today, the day will be 2 milliseconds longer.
Saturn, the second largest planet, is the lightest in the solar system, its density is so low that it would float in water.
Most asteroids lie between the orbits of Mars and Jupiter. Asteroids are a byproduct of the formation of the solar system, more than 4 billion years ago. Dangerous asteroids, ones that could cause major regional or global destruction, only hit the Earth every 100,000 years on average. We can observe more than 20 million meteors every day, but only 1 or 2 meteorites hit the Earth’s surface each day.
