Magnification vs. Resolution - Night Sky Network

1. As you increase magnification (by using different eyepieces), the amount of sky you are looking at will generally get smaller - you are looking a smaller amount of the object you are viewing. The amount of light the telescope is gathering does not change. The resolution of the telescope does not change. The area of sky the scope

Does the Moon Rotate? - NASA

asteroids that pass within 45 million kilometers of the Earth’s orbit. Some near earth objects are potentially large enough to be hazardous to the Earth in the event of a direct collision. Although impact with large objects is rare, the history of Earth indicates that such events do occur. A better understanding of the likelihood
