Through a Telescope

About every two years, Mars reaches its closest point to Earth. However, the distance to Mars at that point varies a lot. Some years, Mars gets twice as close as other years. If Mars is going to be closer than normal, and you have at least a six-inch telescope, you can get a view like this. If Mars isn't near its closest point, all you will see is a dot–no matter how big your telescope is.
