An astronomical archminute consists of 2000 light years. One can define the size of a galaxy by light years or archminutes. the closest spiral galaxy to our own is known as the M31 galaxy in the constillation Andromeda (all facts can be backed up, just search M31 and Andromeda on simple Google search to confirm).
The M31 galaxy is 200,000 light years wide and 100,000 light years high. also known as 100 archminutes by 50 archminutes. of coarse all of these measurements go back to the simple base figure of the speed of light.
1 light year = distance light travels in a year
1 archminute = distance light travels in 2000 years
What else can I help you with?
0.2 kpc per arcminute equals kpc per cm?

What is the angular resolution of the eye?
about 1 arcminute, or 1/60 of a degree ;-) which equates to about 1/3 mm at arm's length
How does an arcsecond measure distance?
An arcsecond is a unit of angular measurement, not distance. It is equal to 1/60th of an arcminute and 1/3600th of a degree. Arcseconds are commonly used in astronomy to specify the size or separation of celestial objects in the sky.
What is the definition of an arcminute in astronomy?
An arcminute in astronomy is a unit of angular measurement equal to 1/60th of a degree. It is used to measure small angles in the sky, such as the apparent size of celestial objects or the separation between two stars.
What is 1 360th of a degree?
One 360th of a degree is known as one arcminute. It is a unit of angular measurement that is equal to 1/60 of a degree. Since there are 60 arcminutes in one degree, this small unit is often used in various fields such as astronomy, navigation, and cartography for greater precision in measuring angles.
When exactly is the moment of sunrise?
Sunrise is the moment when the upper edge of the rising sun appears to be right at the horizon assuming an unobstructed view. That includes the effect of refraction of the sunlight by the atmosphere, which averages about 34 arcminutes. Atmospheric conditions in the sunlight's path to the observer can cause sunrise times to vary by over a minute due to the amount of refraction. At higher latitudes the variation can be many minutes due to the smaller angle between the horizon and the sun's apparent path. For the purpose of calculations, scientists define sunrise to be when the center of the sun is 90.83333° below the observer's zenith. The extra 0.83333°, or 50 arcminutes, accounts for the 34-arcminute average refraction and the 16-arcminute apparent radius of the sun.
What is the resolution of eye in millimeter?
The resolution of the human eye is often described in terms of visual acuity rather than a specific measurement in millimeters. However, it is commonly estimated that the eye can resolve details as small as 1 arcminute, which translates to about 0.3 millimeters at a distance of 20 feet (6 meters). This means that the eye can distinguish between two points that are separated by this distance under optimal conditions.
What is minute degrees?
Minute degrees, or arcminutes, are a unit of angular measurement equal to one-sixtieth (1/60) of a degree. In terms of degrees, there are 60 arcminutes in a single degree. This unit is commonly used in fields such as astronomy and navigation to provide a more precise way of specifying angles or coordinates. Each arcminute can be further divided into 60 arcseconds, making it a finer measurement for detailed calculations.
What is the unit that measures distance around a circle?
The distance around a circle---it's circumference---or the length of some portion thereof---a segment---is measured in linear distance units such as inches, centimeters, feet, or meters. The portion of a circle (the relative distance around) that a segment represents---the segment's circular arc---is measured in units of angular magnitude. In basic geometry and lay usage, the most common angular unit is the degree. In scientific and higher math usage, the most common unit is the radian. The circumference of a circle has an arc of 360° (360 degrees), or 2π rad (2 × pi radians). A radian therefore is equivalent to 180/π degrees. Other units of angular magnitude include the turn (360° or 2π rad), grad (aka gon; 1/400 turn), quadrant (1/4 turn), arcminute (1/60°), and arcsecond (1/60 arcminute).
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.
What is the resolution of the human eye without a magnifying device?
The resolution of the human eye is typically around 1 arcminute, which translates to the ability to distinguish two points that are approximately 0.3 millimeters apart at a distance of about 10 meters. This means that under ideal conditions, a person with normal vision can resolve details down to about 60 pixels per degree of visual angle. However, this resolution can vary based on factors like lighting, contrast, and individual differences in eyesight.
How are light years and astronomical units different?
1 Astronomical Unit (AU) is the average distance between the earth and the sun. It is approximately 149,598,000 km. 1 light year (ly) is the distance light travels in one year. It is approximately 9,460,730,472,580 km The other commonly used astronomical measurement is the parsec. 1 parsec (pc) is the distance at which 1 arcsecond measures 1 AU. It is approximately 3.26156 ly or 30856740079724 km. 1 arcsecond is 1/60 of a arcminute.1 arcsecond is 1/60 of a degree.1 degree is 1/360 of a circle.
