Distance from earth to gps satellite? Navigation satellites move around Earth at an altitude of about  1,243 miles to 22, 223 miles and at about the same speed of  rotation. These satellites are in what is calle â¦ d Medium-Earth  orbits (MEO).
When aerating your lawn, it is best to aerate on a day where the temperatures are milder and the soil in a moist condition, which will make the aerating process much easier. Aerating wet soil can be a real nuisance due to the fact that the plugs will get stuck in the hollow tines and can further compact you soil.
A: No. If your lawn is doing fine and the soil isn't compacted, there's no need to aerate at all. (Aeration involves using a machine that removes finger-sized cores from the soil and deposits them on the surface to create more air space.). If your soil is compacted (and many are), fall is a great time to aerate -- ideally right after a rain when the soil is soft. Some years other goals take precedence, though.
