total lunar eclipse occurred on December 21‚ 2010‚ at 08:17 UTC.[1] Unlike a solar eclipse‚ which can only be viewed from a certain relatively small area of the world‚ a lunar eclipse may be viewed from anywhere on the night side of the Earth. A lunar eclipse lasts for a few hours‚ whereas a total solar eclipse lasts for only a few minutes at any given place‚ due to the smaller size of the moon’s shadow. Also unlike solar eclipses‚ lunar eclipses are safe to view without any eye protection or special

My Solar System Name Period Introduction: Every physics student has had a lot of experience with the force of gravity. Unfortunately‚ this experience is limited to the interaction between a very large object‚ the Earth‚ and much smaller objects that are very close to it. This is a very limited range of the possibilities. Software simulations of gravity allow physics students to explore a variety of other gravitational interactions between objects. These activities are designed to be used
