To be precise about it, it varies somewhat, depending on the moon's distance from the earth,
just as you'd expect.
At the time of the full moon on December 31, it was 33' 57", or 2,037 arc seconds ... about 10%
larger than 1/2 degree.
At the time I'm writing this ... 11 days after that full moon ... the moon's apparent visual diameter
is 30' 25", or 1,825 arc seconds ... about 10.4 % smaller than 11 days ago, and now just 1 % larger
than 1/2 degree.
What else can I help you with?
Whats the angular size of long thin cloud that is stretched straight over head to the horizon would have?
The angular size of the cloud would depend on its length and how far it extends from directly overhead to the horizon. Assuming the cloud is very long and extends all the way to the horizon, it would have a wide angular size approaching 180 degrees when looking from directly underneath it.
Is the same size as earth has no moons and has thick atmosphere of mostly carbon dioxide?
The planet you are describing matches the characteristics of Venus. Venus is nearly the same size as Earth, has no moons, and its atmosphere is mostly composed of carbon dioxide, with thick clouds of sulfuric acid.
Angular silt-size particles deposited by wind?
Angular silt-size particles deposited by wind are known as loess. Loess deposits are characterized by their fine-grained, silty texture and angular shape, which result from the wind transporting and depositing these particles over time. These deposits can be found in regions with arid or semiarid climates, where they form thick layers of fertile soil.
What is half the size of earth has two moons and has a atmosphere of mostly carbon dioxide?
The planet that is half the size of the earth, has 2 moons, and has an atmosphere of mostly carbon dioxide is Mars. The average length of a day on Mars is 37 minutes longer than that of the Earth.
What planet has 34 moons?
No planet in the solar system has that number of moons. There is a gap in numbers between Saturn's 63 known moons and Uranus' 27 known moons.
Converting AU into arc seconds?
In Converting AU into arc seconds first of all you will need to convert our angular size from arcminutes to arcseconds
How far is star Betelgeuse is from earth?
Studies since 1990 have produced an angular diameter (apparent size) ranging from 0.043 to 0.056 arcseconds.
Use the small-angle formula to find the angular diameter of mars when it is closest to Earth how does that compare with the maximum diameter of Jupiter?
The small-angle formula is θ = 2 * arctan(d / 2D), where θ is the angular diameter, d is the physical diameter, and D is the distance from the observer. When Mars is closest to Earth, its angular diameter is around 25 arcseconds. This is smaller compared to the maximum angular diameter of Jupiter, which can reach up to around 49 arcseconds due to its larger physical size.
How big does neptune look from earth?
Neptune appears as a small, bluish dot when viewed from Earth. Its angular size varies depending on its distance and position relative to Earth in its orbit around the sun. On average, Neptune's angular diameter is about 2.3 arcseconds when viewed from Earth.
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)
If you triple your distance from an object what happens to its angular size?
If you triple your distance from an object, its angular size will appear smaller. This is because angular size is inversely proportional to distance – as distance increases, angular size decreases.
How many moons placed next to each other would extend from one point on the horizon to the point on the opposite side of the horizon?
It would take approximately 360 moons placed next to each other to extend from one point on the horizon to the point directly opposite on the horizon, assuming each moon is the same size as Earth's moon.
Angular distance in astronomy?
Angular distance in astronomy refers to the separation between two celestial objects as seen from Earth. It is usually measured in degrees, arcminutes, or arcseconds. This measure helps astronomers locate and describe the positions of objects in the night sky.
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 is the size of the smallest feature visible on Jupiter at 4.2 AU The hubble space telescope has an angular resolution of 0.05?
The resolution of the Hubble Space Telescope at a distance of 4.2 AU is about 207 km. At this distance, the smallest feature visible on Jupiter would need to be larger than 207 km to be resolved by the telescope based on its angular resolution of 0.05 arcseconds. Smaller features would appear blurred or indistinct.
