Depending on where the moon is in its orbit, that angle can be anything.
For example:
-- At any New Moon, it's a couple of degrees or less.
-- During any solar eclipse, it's 1/2 degree or less.
-- During a total solar eclipse, it's zero.
-- At First Quarter or Last Quarter, it's within a degree or two of 90 degrees.
-- At Full Moon, it's within a degree or two of 180 degrees.
-- During any lunar eclipse, it's within 1/2 degree of 180 degrees.
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.
More or less. There is a law of conservation of angular momentum, according to which Earth can't gain or lose angular momentum on its own - if for example it loses angular momentum, it has to go somewhere. A meteor who falls into the Earth, or a rocket leaving the Earth can change Earth's angular momentum - but the total angular momentum (e.g., of the system meteor + Earth) is the same, before and after the impact.

Since Earth has about 4 times the diameter of the Moon, the angular diameter of Earth, as seen from the Moon, is about 4 times larger than the angular diameter of the Moon, as seen from Earth. Since the Moon's angular diameter as seen from here is about half a degree, that would make Earth's angular diameter about 2 degrees.If you wish, you can look up more exact figures and do more precise calculations, but it is hardly worth the trouble, since there is some variation in the distance from Earth to Moon anyway.
No, the center of mass between Earth and the sun is not exactly halfway between the two because the sun is much more massive than Earth. The center of mass is closer to the center of the sun, but it is not exactly at the halfway point.
Angular separation between images is the apparent angle between two objects in the sky as observed from a specific point on Earth. It is a measure of how far apart the two objects appear in the sky. It is often measured in degrees or arcminutes.

Oh, what a lovely question! When we talk about the angular separation between two celestial bodies, we're basically looking at the distance between them as seen from Earth. It's like measuring the space on a beautiful canvas, and every angle just brings more depth and wonder to the painting of the night sky. Just remember to admire the space between those stars and planets, as it adds such a delightful dimension to the vast universe.
To determine the angular distance between two points in a celestial sphere, one can use spherical trigonometry or coordinate systems such as right ascension and declination. By calculating the difference in these coordinates for the two points, the angular distance can be found.

The angular distance between two points on a sphere can be calculated using the Haversine formula, which involves the latitude and longitude of the two points. The formula takes into account the Earth's radius and computes the central angle between the points, which can then be converted to angular distance.
Because Venus orbits closer to the Sun than the Earth, the angle between Venus and the Sun can never reach 180 degrees (the Sun and Venus cannot be directly opposite each other, or in "Opposition", as viewed from Earth). Assuming circular orbits for Earth and Venus of 149.6 million km and 108.2 million km respectively, and that the Earth and Venus orbit in the same plane, one can use trigonometry to find that the maximum angular separation between Venus and the Sun is approximately 46.3 degrees.
During the waning phases of the moon, the angular distance from the Sun is generally increasing. This is because, as the moon transitions from a full moon to a new moon, it moves away from the Sun in the sky, resulting in greater angular separation. Consequently, the waning phases reflect the moon's orbit around Earth, causing this increasing angular distance.
The center of the moon is within a few thousand miles of the straight line between the center of the sun and the center of the earth.
The gravitational force between the earth and a body at the center of the earth would be 0 Newtons or 0 lbf. F=G (m1*m2)/r^2 r = zero if the center of the body is at the center of the earth
