... Kepler's Laws . ... Second Law . 12a. More on 2nd Law . ... Kepler's 2nd law prescribes the way the velocity V of an object orbiting a single center varies around its orbit: . The rate at which the line to the center ("radius vector") covers area does not change around the orbit." As noted in section #12 , this means that the object's velocity V increases when its distance r decreases, and vice versa. ... Because by Kepler's 2nd law, the Earth moves in its orbit a little faster in winter. ...

... We can help students grasp the significance of Hubble's extremely keen eye, and learn a bit about angles and math in the process, with the following in-class activity. ... Looking through binoculars or telescopes allows us to magnify a small section of the sky. To measure sizes or distances in that small section, astronomers divide a degree into 60 smaller pieces called arcminutes, and further subdivide minutes into 60 smaller sections called arcseconds. ... 30 feet = . ... 36 seconds . ...

An extra leap second has to be inserted at the end of 2008, so this is how you should count down on New Year's Eve to celebrate the start of the International Year of Astronomy according to Irish astronomers. The extra second is needed to bring the uniform measure of time used by physicists using atomic clocks back into nearly exact agreement with time as measured by the rotation of the Earth. ... There will be national and international events organized throughout the year to mark the occasion. ...
