It is difficult to imagine the difference in size between the Sun and Earth, or the distance between them. This activity will help you to visualise it. If you create this model, the Earth and Sun ...

Then they used the model to reverse-engineer the mesospheric conditions that would allow scientists' few findings to take shape. The results, dubbed JAWARA, offer the longest-ever look at Earth's ...

This model uses circular orbits to approximate the paths of Mars and Earth. It uses 3:2 as the ratio of their orbital radii (the actual is about 1.524:1), and it uses a ratio of 2:1 as the ratio of ...

Abstract: This review article aims to give a comprehensive review of periodic orbits in the circular restricted three-body problem (CRTBP), which is a standard ideal model for the Earth-Moon system ...
