Let's know about our EARTH

·        A photo of the Earth has been taken from a distance of 3.7 billion miles.

·        A human being can survive unprotected in space for about two minutes.

·        There are really only 23 hours, 56 minutes, and four seconds in a day, not 24 hours.

·        A solid iron ball 1,500 miles wide sits at the centre of the earth. The temperature there is about 9900 Degrees Fahrenheit.

·         Earth and mercury are the two densest planets in the Solar System.This means that particles inside the planet are most closely packed together.

·         Earth is gradually slowing down. Every few years, an extra second is added to make up for lost time. Millions of years ago, a day on Earth will have been 20 hours long. It is believed that, in millions of years time, a day on Earth will be 27 hours long.

·         From a distance, Earth would be the brightest of the planets. This is because sunlight is reflected off the planet's water.

·        The Earth weighs 5,980,000,000,000,000,000,000 tonnes.

·         Planet Earth rotates around the sun at approximately 1000 miles per hour.
