A second of arc (arcsecond, arcsec) is 1⁄60 of an arc minute, 1⁄3,600 of a degree.
When it comes to astronomy, you will find the term "arc second" used in three ways: (1) to express a given distance in declination on a star chart, (2) as a given unit of an astronomical object's size, and (3) as an expression of a telescope's resolving power.

Will Sirius B eclipse Sirius A this New Year's Eve in 2012?
No, for several reasons. The first and most important is that Sirius B and Sirius A have, as seen from Earth, a minimum angular separation of 3 arcseconds. They never eclipse each other. Also, Sirius B is much smaller than Sirius A, and they're at about the same distance from Earth, It's too small to block more than a miniscule fraction of light from Sirius A. A more accurate description of what would be seen from Earth if it could actually line up with A would be a "transit", not an eclipse. Finally, periastron occured in 1994. The two stars have actually been moving further apart since. Since the period is about 50 years, the next time they're close together won't be for another three decades, and certainly not this year.

How many degrees are in 36000 arcseconds?
There are 10 degrees in 36,000 arcseconds. There are 3600 arcseconds in a degree, and 36,000 divided by 3,600 is 10.
How many arcseconds are in 3 degrees?
3 Degrees to Arcseconds = 10,800
How many arcseconds in 5 degrees?
5 degrees is 18,000 arcseconds.
What get the most sunlight?
More solar radiation reaches Jupiter than any other object, because it occupies more of the sun's "field of vision" than any other object. In other words, as seen from the sun, Jupiter "looks biggest," as a near-circle whose average diameter spans an angle of 37 arcseconds.Here is a list of the planets in order by average apparent size as seen from the sun:Jupiter (37.04 arcseconds)Venus (23.07 arcseconds)Earth (17.57 arcseconds)Mercury (17.38 arcseconds)Saturn (17.34 arcseconds)Mars (6.13 arcseconds)Uranus (3.67 arcseconds)Neptune (2.27 arcseconds)
How many meters in 3.8 arcseconds?
It is impossible to convert arcseconds into metres without knowing the scale of angle measurement.
Arcseconds in one degree of angle?
3600
How many arcseconds are in one degree?
3600 seconds.
What is the wobble?
It amounts to 0.7 arcseconds (about 15 meters on the Earth's surface) and has a period of 433 days.
How distant is a star with a parallax of 2 arcseconds answer in parsecs?
The reciprocal of the 2 - that is, 1/2 or 0.5.
What is the earth's wobble?
It amounts to 0.7 arcseconds (about 15 meters on the Earth's surface) and has a period of 433 days.
How many arcseconds are there in one degree?
1 minute = 60 seconds1 degree = 60 minutes = (60 x 60) = 3,600secondsAn arcsecond is simply a second in terms of degrees. There are 60 arcseconds in one arcminute, and 60 arcminutes in one degree. Therefore, there are 3,600 arcseconds in one degree. This is determined by multiplying 60 by 60, and this equals 3,600.
Formula to calculate distance between planets?
The parallax method can be used to calculate the distance between planets and other celestial bodies. The formula for this is d(pc) = 1/p where p is parallax measured in arcseconds.
