MIKE ANTLER: The distance between the Earth and the Sun is approximately 93 million miles or 150 million kilometers. To give you a sense of how far that is, if we were to lay 93 million standard-sized cars end-to-end, they would stretch around the Earth's equator more than 3.5 times! Alternatively, if you were to travel at the speed of light (about 186,000 miles per second), it would take you about 8.3 minutes to travel from the Sun to the Earth. //////////////////////// ME: What is the size of a T-Rex? MIKE: The size of a Tyrannosaurus Rex, or T-Rex, is estimated to be around 40 feet (12 meters) in length and 15 to 20 feet (4.5 to 6 meters) in height at the hips. To help you visualize this, the length of a T-Rex is equivalent to about 3 cars parked end-to-end, while its height is about the same as a 2-story building. Additionally, its skull alone could be up to 5 feet (1.5 meters) long, which is about the height of an average adult human!
