What is the angular diameter of the moon?
Well, isn't that a wonderful question! The angular diameter of the Moon can vary from around 29 to 34 arcminutes because of its elliptical orbit around Earth over time. Imagine holding a pencil at arm's length - that's like how your eyes see the Moon in the sky, changing and dancing with the night. Happy exploring!
How can one determine the angular diameter of an object in the sky?
To determine the angular diameter of an object in the sky, you can use trigonometry. Measure the actual size of the object and its distance from you, then use the formula: Angular diameter = 2 * arctan (object size / (2 * distance)). This will give you the angle in degrees that the object subtends in the sky.
Name of bright star in western sky just above the horizon in Missouri?
The bright star you are likely observing in the western sky just above the horizon in Missouri is probably the planet Venus. Venus is often visible as the brightest object in the sky after the sun and the moon.
How many degrees above the horizon is the big dipper?
The Big Dipper is located roughly 30-60 degrees above the northern horizon depending on your location and the time of year. It is a circumpolar constellation, meaning it is visible all year round in the northern hemisphere.
How do you use the word horizon in a sentences?
My goal is just over the horizon.
I am given the bolometric BC equals -1.46 and the visual magnitude V equals 4.33 of a star. how do you calculate the angular diameter?
The bolometric correction allows you to convert between visual and bolometric (total) magnitude - where the bolometric magnitude includes all radiation emitted by the star, not just visible light. It has nothing to do with the angular diameter.

How many degrees above the horizon does the upper edge of a rainbow usually reach?
The altitude of the highest point of the rainbow that you see is (42 degrees) minus (the altitude of the sun above the horizon behind you). If the sun is sitting right on the horizon ... just risen or just about to set ... then the highest point of the rainbow is about 42 degrees above the horizon opposite the sun. If the sun is higher, then the rainbow is lower, by the same amount. If the sun is more than about 42 degrees above the horizon, then any rainbow you might otherwise see is entirely below the opposite horizon, and you don't see one.
Does an optical telescope and a radio telescope of the same size have the same angular resolution?
No, they do not. The angular resolution of a telescope is determined by the wavelength of the radiation it is measuring and its diameter. Since optical telescopes detect shorter wavelengths than radio telescopes, they generally have better angular resolution for viewing fine details.
What soil horizon contains only partly weathered rock?
The C horizon, also known as the parent material horizon, contains only partly weathered rock. This layer is located just below the B horizon and above the solid bedrock of the R horizon in the soil profile. It is characterized by a mixture of weathered rock fragments and some organic matter.
What is the Angular size of a circular object with a 1 inch diameter viewed from a distance of 2 yards?
Since it is a small angle, just divide the diameter by the distance. Be sure to convert everything into the same units first. The answer will be in radians.
Name of bright star in western sky just above the horizon in Missouri?
The bright star you are likely observing in the western sky just above the horizon in Missouri is probably the planet Venus. Venus is often visible as the brightest object in the sky after the sun and the moon.
What does on the horizon mean?
The "horizon" is the furthest you can see. "On the horizon" therfore refers to an object which is just in sight.
How many degrees above the horizon is the big dipper?
The Big Dipper is located roughly 30-60 degrees above the northern horizon depending on your location and the time of year. It is a circumpolar constellation, meaning it is visible all year round in the northern hemisphere.

How far can you see to the horizon on water?
A very rough or "ball park" figure is about 20 miles. Comment: It depends on your height above the water. You could only see 20 miles if you were well above sea level. If you are standing more or less at sea level, with your eyes just a few feet above the water level, you could see only about 3 or 4 miles. For example: Eye level at 6 feet: horizon at about 3 miles. Eye level at 24 feet: horizon at about 6 miles. Eye level at 96 feet: horizon at about 12 miles. Eye level at 270 feet : horizon at about 20 miles.
