There are actually a number of different techniques that are used to estimate the distances of various astronomical objects. You can study the spectrum of the light (or any electromagnetic emission) from that object, and determine how much of a Doppler red shift there is (it's almost always a red shift, very few objects are approaching the Earth) and since the general rate of expansion of the universe is known, we can determine from the size of the red shift how far away something is. If the nebula is associated with a Cepheid variable star, then from the rate of variation and the brightness of the star, we have another clue. And, if we observe the nebula at two different seasons of the year, when the Earth is at opposite sides of the solar system, we may be able to get some parallax for a geometrical calculation, but that depends upon how far away the nebula is; if it is extremely far away, we don't have enough parallax to do it.

How far away from earth are nebulae?
Nebulae can vary in distance from Earth. Some are close, within a few hundred or thousand light-years, while others can be many thousands or even millions of light-years away. The closest known nebula to Earth is the Helix Nebula, which is about 700 light-years away.
Grab nebula was first seen on earth in 1054 how long did it take to get here?
The Crab Nebula is about 6,500 light-years away from Earth. Since one light-year is the distance light travels in one year, it took 6,500 years for the light from the Crab Nebula's explosion in 1054 to reach Earth.
What is a name for the apparent movement of a star used to measure its distance from earth?
parallax
What is the distance of the Orion nebula to the milky way?
The Orion Nebula is located approximately 1,344 light-years away from Earth within the Milky Way galaxy. A light-year is the distance that light travels in one year, which is about 9.461 trillion kilometers. Therefore, the distance between the Orion Nebula and the Milky Way is about 12.7 quadrillion kilometers. This vast distance is measured using astronomical units to provide a sense of scale in the vastness of space.
What is the measure of the earth's pull on an object?
The measure of the Earth's pull on an object is called its gravity, which is commonly quantified as the object's weight. This force is determined by the mass of the object and the mass of the Earth, as well as the distance between them.
What is the distance from earth to the crab nebula?
The distance from Earth is about 6,500 light years (2000 parsecs).
Are stars at the center of the milky way closer to earth that Orion nebula?
Distance to center of Milky Way: about 26,000 light-years. Distance to Orion Nebula: about 1,300 light-years.
How far is the nebulae from the sun?
The Orion Nebula is a distance of 1,344 ± 20 light years from the Earth. Based on the plus or minus 20 light years, it doesn't matter if you measure from the Earth or the Sun. The accuracy is within the tolerance range.
What is used when astronomers measure the distance from the sun to the earth?
Parallax is the method that astronomers use to measure the distance from the sun to the earth.
Which measure is not considered when measuring absolute magnitude?
Distance. Absolute magnitude is a measure of the intrinsic brightness of a star, independent of its distance from Earth.
Is a nebula further from earth than a galaxy?
Earth is IN a galaxy - as is the nebula.
What is the distance from earth to the sun in Celsius?
Celsius is a measure of temperature, not distance.
How far is the proxima centauri to earth by walking?
The distance between two points is the distance between them. It doesn't depend on the method an object uses to move between the two points. It also doesn't depend on what route an object follows between them, or even whether or not anything moves between the two points. The distance between the earth and the Orion Nebula is the distance, even though no object has ever moved between the earth and the Orion Nebula.
What mathematical equation describes how to measure the distance from earth to the moon using earths diameter as a unit of measure?
The mathematical equation which describes how to measure the distance from Earth to the moon using Earth's diameter as a unit of measure is d = Dcot(p/2)/2 Where d is the distance from Earth to the moon, D is the diameter of the Earth and p is the angle of parallax subtended at moon by the diameter of the Earth.
How far is trifid nebula from the Earth?
The Trifid Nebula is about 5,200 light years away from Earth.
How many normal years is Rigel from Earth?
"Normal Years" is a measure of time. "Rigel from Earth" is a measure of distance. There is no answer to this question.
How do you measure the distance from the earth to the sun?
with feet, or with km..... :P
