<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>I was outside Saturday Night at about 9:30-9:45pm looking for the envisat, and all of a sudden this VERY bright, VERY FAST object shot across the front of my house. This was the fastest object i have ever seen in the sky, it looked to be WAY faster than even any shooting star i have ever seen. What was this object? anyoone have any ideas? it was in and out of sight all in about 2seconds..it was awsome though.. <br /> Posted by Cassini12</DIV></p><p>Actually, 2 seconds sounds about right for a shooting star....maybe even a bit leisurely. I've seen many that last less than a second. How fast they last depends on the speed they are moving when they are striking the Earth's atmosphere. The minimum speed is 11 km per second, and the fastest are up to 73 kps. The Geminids are known to be slower, and the Leonids much faster. Sporadic meteors, which is what you usually see before midnight, are typically not the fastest, since the Earth is not running into them head-on.</p> <div class="Discussion_UserSignature"> </div>
