In 1862, a famous Irish physicist and mathematician, Lord Kelvin, estimated that Earth was between 20-million and 400-million years old. While that is an enormous span of time, even an age of 400 million years would make the planet quite … WebIf a planet is close to the Sun, the distance it orbits around the Sun is fairly short. This distance is called an orbital path. The closer a planet travels to the Sun, the more the Sun’s gravity can pull on the planet. The stronger the pull of the Sun’s gravity, the faster the planet orbits. Check out how long a year is on each planet below! down\u0027s plumbing
