The only thing that can be directly observed is a galaxy's apparent size (angular size). Since galaxies come in different sizes, this can only give a rough idea of the galaxy's distance from Earth.

How far is the earths moon from mercury?
Varying from the the distance from the Earth to the Moon + the distance from the sun to the earth + the distance from mercury to the sun, to the distance from the earth to the sun - the distance from mercury to the sun - the distance from the earth to the moon
Which distance measurement is most useful in measuring the distance between stars?
There are two in common use; the "light year", which is the distance that light travels in one year, and the "parsec". The parsec is a "parallax-second of arc", the distance that an object would be from Earth if it appears to be separated by one second of arc as viewed from one side of the Earth's orbit and from the other side of the Earth's orbit. The "parsec" is approximately equal to 3.26 light years. For intergalactic distances, many astronomers use the "mega-parsec", one million parsecs distance, abbreviated as "Mpc".
Are the moon and the sun the same distance from earth?
No, the moon and the sun are not the same distance from Earth. The average distance from the Earth to the moon is about 238,855 miles, while the average distance from the Earth to the sun is about 93 million miles.
Whats the distance from earth to the moon?
The distance from the moon to the Earth is 238,900 miles.
The sun is 93000000 miles from the earth this distance is an .?
The average distance from the Sun to the Earth is one "astronomical unit" or "AU".
Why isn't a galaxys size alone useful in determining its distance from Earth?
The only thing that can be directly observed is a galaxy's apparent size (angular size). Since galaxies come in different sizes, this can only give a rough idea of the galaxy's distance from Earth.

How rocks layer useful in determining the age of the earth?
they are useful by showing where the fossil is buried then on that certain layer, it will be studied to know the age.
What is your galaxys name?
People on Earth call it the Milky Way (in English).
IF Earth's magnetic north pole is not located at the geographic north pole why is a compass useful for determining direction?
A compass is still useful for determining direction because it points towards the magnetic north pole, providing a consistent reference point that helps in navigation. Even though the magnetic north pole and geographic north pole are not aligned, the difference can be accounted for using magnetic declination adjustments.
What is most useful for measuring the shortest distance between two places on the earth and path between them?
Globe
What is the most accurate method for determining the distance to a nearby galaxy?
The most accurate method for determining the distance to a nearby galaxy is through the use of parallax measurements, which involve observing the slight shift in position of the galaxy against background stars as the Earth orbits the Sun. This method allows for precise calculations of the galaxy's distance based on trigonometry.
What are the factors that contribute to determining the luminosity scores of celestial objects?
The factors that contribute to determining the luminosity scores of celestial objects include their size, temperature, and distance from Earth. Larger and hotter objects tend to have higher luminosity scores, while objects that are closer to Earth appear brighter.
What is educational attainment?
In addition to correctly determining the size of the Earth and finding correct methods for determining the size of the Moon and the distance to the Moon and Sun, he was the head of the largest library in the western world (Alexandria in northern Egypt) and must have had many students.
What would happen if the earth were closer to Jupiter?
Considering the distance of Jupiter to the Sun, the Earth would suffer from an utter and never ending ice age, because the heat from the Sun is the major determining factor in the climate of our ecosystem.
