... 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. ...

... The common identifier of this star system is G89-14. Initially, there were known just two close spectroscopic components in this system, A and B, orbiting around each other with a period of about 190 days (Carney et al., ... Subsequently, at a separation of 34 arc seconds from this spectroscopic pair, Allen et al. (2000) found its companion D with common proper motion (Fig.1, right, and Fig.2). ... The uniqueness of this star is that it is the most metal-poor quadruple system known to date. ...

Hubble Finds Oxygen Atmosphere On Jupiter's Moon Europa . Astronomers using NASA's Hubble Space Telescope (HST) have identified the presence of an extremely tenuous atmosphere of molecular oxygen around Jupiter's second moon, Europa . ... Europa's oxygen atmosphere is so tenuous that its surface pressure is barely one hundred billionth that of the Earth," said Principal Investigator Doyle Hall, of Johns Hopkins. ... The oxygen gas slowly leaks into space and must be replenished continuously. ...

... When the Voyager 2 spacecraft flew by the planet Uranus in January 1986, astronomers were treated to their first close-up glimpse of the satellites that orbit the seventh planet. ... But by far the most intriguing of those 15 satellites was a jigsaw-puzzle world called Miranda . ... How dark was it at Miranda? One of the Voyager scientists put it this way: Taking pictures in the Uranus system is like trying to do photography in a ballpark at night when the only light comes from a single candle. ...

... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...

... Needs for precise timing There exists a broad spectrum of needs for precise timing, extending from the most demanding requirements of satellite navigation systems for a continuous atomic time scale accurate at the level of nanoseconds, through the increasing number of precise time- stamping or dating systems working at the level of milliseconds, to the far end of this spectrum where space geodesy, space navigation and astronomy require the orientation of the Earth at the level of microseconds. ...
