... For this exercise we will construct a scale model of the solar system. In a scale model, the size is reduced while accurately maintaining the relative proportions of all of the features included in the model. For our solar system, we will use a scale of 10,000 kilometers (approximately 6,200 miles) ...

Equilibrium Tides
... tides are due to gravity of sun and moon; so it’s natural to think tides would happen only once a day, like the sunrise or the moonrise. In fact, the statement “tides are caused by the gravity of the sun and the moon” is inadequate in an important way, and understanding this point holds the key to t ...

Barnard’s star is actually moving towards us at 107 km/s, and in about 10,000 years it will pass within 3.8 ly of us; after that its distance will increase again. When it is 3.8 ly away it will be the nearest star. Wil ...
