... 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. ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . The distance of the Sun from Earth is the basic unit of all astronomical distances. ... The 18th century transits of Venus allowed a proper geometrical determination of this unit to be made for the first time. ... One of the most famous of these problems is the black drop effect. ... They calculated the mean distance to the Sun to be 95 million miles whereas the currently accepted value is close to 93 million miles. ...

... The greater the distance, the smaller the parallax. ... That triangle has the same proportions as the much larger triangle ABC, and therefore, if the distance B'C to the thumb is 10 times the distance A'B' between the eyes, the distance AC to the far landmark is also 10 times the distance AB. ... The most distant objects our eyes can see are the stars, and they are very far indeed: light which moves at 300,000 kilometers (186,000 miles) per second, would take years, often many years, to reach them. ...

... 2015 January 29 . Close Encounter with M44 . ... Explanation: On Monday, January 26, well-tracked asteroid 2004 BL86 made its closest approach, a mere 1.2 million kilometers from our fair planet. ... The remarkably pretty telescopic field of view includes M44, also known as the Beehive or Praesepe star cluster in Cancer. Of course, its close encounter with M44 is only an apparent one, with the cluster nearly along the same line-of-sight to the near-earth asteroid. ... About APOD | ...

We present a characterization of the close environment of GRB 980425 based on 5-160 ЮМm spectro-imaging obtained with Spitzer. The gamma-ray burst GRB 980425 occurred in a nearby (z = 0.0085) SBc-type dwarf galaxy at a projected distance of 900 pc from an H II region with strong signatures of Wolf-Rayet (WR) stars. ... This atypical property is rarely observed among morphologically relaxed dwarfs, suggesting a strong causal link with the gamma-ray burst (GRB) event. ... ADS Citation Query . ...

. Next: Triple with velocity curves Up: Fit scenarios Previous: Single-lined spectroscopic binary with Contents . Select all three masses as fit parameters. The mass ratio of the close pair will be constrained, but as far as the absolute masses, this system is identical to a single-lined binary. Christian Hummel 2015-04-28

... There isn't really any need for this section because SM doesn't distinguish between hardcopy devices such as laser printers and other devices such as graphics terminals, except that it saves up plotting commands for hardcopy devices and sends them all when you are finished. ... The two commonest incantations are probably device $printer playback device x11 or device $printer my_macro device x11 which can be simplified to hcopy and hmacro my_macro respectively. ...

... Planets . ... Earth Satellites . ... Looking in the direction of the constellation Cygnus the Swan and launched by NASA in 2009 is the Kepler Space Observatory.Many previous missions searching for exoplanets mainly detected large giant planets, like large hot Jupiters (it is easier to detect larger planets).However KeplerтАЩs main objective is to search for much smaller planets located in a habitable zone which is not too close nor too far from their star; planets which may be just like our Earth. ...

LadyBug Power Monitor - Attenuators Document No. ... If we add this to the directional coupler attenuation, we will get 89.82dB total. ... We are surements of the attenuators attached to the LadyBug using 90.02dB in the LabVIEW application. power sensors placed at the Gregorian Dome (GD) and Carriage House (CH). ... Conclusion 3 Total Attenuation There is a slightly difference between the previous measurements of the attenuators in 2010, and the total attenuation measured during this exercise. ...

A lot of astronomers and news media are saying about how close it will be and how big it will look, but they are leaving out two crucial facts: Mars will be nearly 56 million kilometers away, and it's only fractionally closer than the last favorable pass. ...
