Over several years the apparent size of the sun as viewed by an observer on Earth will?

i believe the answer is it will vary in a cyclic manner because the earth moves farther away from the sun in summer in the northern hemisphere and then closer in the winter

What is an apparent magnitude?
Earth's apparent magnitude would depend on where it is viewed from. For instance, from Saturn, the apparent magnitude is 1.45. From Mars is would be somewhat higher.
What does apparent magnitude depend upon?
apparent magnitude (brightness of a star when viewed from Earth) depends on the size of the star, how hot it is, and its distance from Earth
What is a stars brightness as if it were a standard distance?
Theres `Absolute Magnitude` which is the brightness of a star at a set distance. Then there is `Apparent Magnitude` which is the apparent brightness from earth, regardless of distance.
What is retrograde motion as applied to a planet?
The "apparent" reverse or backwards motion of a planet as observed from Earth. The innermost planets appear to have a retrograde motion when viewed from Earth.
Which star is brighter Vega or Betelgeuse?
Brightnest is a factor of luminousity and distance as seen from Earth. (Apparent magnitude)Vega - 0.03.Betelgeuse: 0.42So Betelgeuse is brighter as viewed from Earth.
What is an apparent magnitude?
Earth's apparent magnitude would depend on where it is viewed from. For instance, from Saturn, the apparent magnitude is 1.45. From Mars is would be somewhat higher.
What is the name of the brightness of a star viewed from earth?
Apparent magnitude.
What is the star with the brightest apparent magnitude as viewed from Earth?
Sirius.
What does apparent magnitude depend upon?
apparent magnitude (brightness of a star when viewed from Earth) depends on the size of the star, how hot it is, and its distance from Earth
Why does the ecliptic show?
The ecliptic is the apparent path of the sun's movement in space, as viewed from the earth.
Compare and contrast apparent magnitude and absolute magnitude?
Apparent Magnitude is the star's brightness as it appears from earth. absolute magnitude is the apparent brightness of a star if viewed from a distance of 32.6 light years away.
Compare apparent magnitude and absolute magnitude?
Apparent Magnitude is the star's brightness as it appears from earth, while, Absolute Magnitude is the apparent brightness of a star if viewed from a distance of 32.6 light years away.

What is retrograde motion as applied to a planet?
The "apparent" reverse or backwards motion of a planet as observed from Earth. The innermost planets appear to have a retrograde motion when viewed from Earth.
What direction relative to an observer on the earth's surface does the moon travel in its orbit?
In this case, there is 'true' motion, and there is 'apparent' motion. To an observer on earth, the moon 'appears' to rise in the east and set in the west, just like the sun. But in fact the moon travels from west to east in its orbit around the earth. From a perspective far about the earth and to the north, the moon travels counter-clockwise around the earth. It is the relatively rapid daily spin of the earth from west to east that causes the apparent motion. The moon takes a whole month to orbit earth; in that time 27+ days have gone by on earth.
What does the apparent motion of objects in the sky depend?
The apparent motion of objects in the sky depends on the motions of Earth.
What variable of apparent brightness is eliminated when discussing absolute brightness?
Distance. "Absolute magnitudes" are all calculated as if viewed from the same distance, while "apparent magnitude" is how bright the star appears to be as seen from Earth.
