The Sun : Hot hot hot hot and hot!


The Sun is the Earth’s nearest star, about 150 millions km away. It is a medium-sized star, and belongs to a group of star types that astronomers call ‘main sequence’ stars. Most of these, including the Sun, will burn for about ten billion years before expanding and cooling to become red giants, ultimately using up all their fuel. The Sun is about halfway through its lifetime.

The Solar System : Traveling around the Earth!

comets, dust and gas. The planets, asteroids and comets travel around the Sun, the centre of our Solar System.

Space Station : Living in the space


A space station is a structure designed for human beings to live on in outer space, for periods of weeks, months, or even years. They are used to study the effects of long-term space flight on the human body and to carry out scientific experiments in space. Space stations do not have a major propulsion system and are unable to land back on Earth, Instead, other vehicles are used to transport crew, equipment and supplies to-and-from the station.
