Subject: Re: [LPNY DISCUSS] (OT)Blay's astounding insight Date: Mon, 29 Sep 2003 19:12:21 -0400 To: From: Bob Armstrong It's the difference between solar time ( with respect to the= sun ) and sidereal time ( with respect to the stars ) >From = http://astrosun.tn.cornell.edu/courses/astro201/sidereal.htm The Earth must rotate an extra 0.986 degrees between solar= crossings of the meridian. Therefore in 24 hours of solar= time, the Earth rotates 360.986 degrees. A sidereal day lasts from when a distant star is on the= meridian at a point on Earth until it is next on the= meridian. A sidereal day lasts 23 hours and 56 minutes (of = solar time), about 4 minutes less than a solar day. -- On Mon, 29 Sep 2003 17:26:04 -0400, Gary Popkin wrote: >=A0>From: "Gary Popkin" >=A0> >=A0>Wow!!
