Welcome to our Physics lesson on Earth and Planets, this is the second lesson of our suite of physics lessons covering the topic of Earth and Other Celestial Bodies, you can find links to the other lessons within this tutorial and access additional physics learning resources below this lesson.
Earth and Planets
Planets are big spherical-shaped celestial bodies that revolve around the Sun. The trajectory of planets is known as their orbit and each orbit has an elliptic shape. In other words, the orbit represents the path followed by a planet during their revolution around the Sun. Planets are visible because they reflect the light incident from the Sun. In ancient times, people were able to identify six planets: Mercury, Venus, Mars, Jupiter, Saturn and obviously, the Earth. The other two planets, Uranus and Neptune were discovered in recent centuries as well as Pluto, which until a few years ago was considered as a planet but now it is not classified as such anymore due to its small dimensions. The following figure represents a simplified illustration of the solar system.
All planets of the solar system have been explored using space probes. However, humans have not been able to physically travel to any of them due to the large distance and technical difficulties though there are asperations for humans to travel to the planets within our solar system and beyond once technological advances permit this..
