Radar.
No, seriously. Scientists have used radar to measure the distance to the Moon since radar was invented. (Nowadays they don't need to; the Apollo astronauts placed a laser reflector on the Moon to make it easier to measure the precise distance to the Moon any time the want.)
For things farther out, parallax measurements between two observatories precisely measuring the angle between, say, Neptune and a nearby star will allow astronomers to measure the distance quite accurately anywhere in the solar system.
They can even use similar techniques to measure the distance to nearby stars, although the angles involved are very tiny.

∙ 13y agoOn average, the distance between the earth and the sun is 93 million miles. you can measure it anyway you like, but a light year is defined as the distance light can travel in one year.
Lights moves at the speed of 186,000 miles per second. Therefore, light
from the sun does not take a year to reach us, since it is, by comparison
with other starts, relatively close to us

∙ 10y agoWe use the amount of the Red shift/Blue shift, which is created by the Doppler Effect to work out how fast an object is moving away.
When a space object is getting futher away from us/getting closer to us, the frequency of the visible light increases, which means that if the object is bright enough, it will turn red (because red light has a higher frequency, than the visible light).
If we know the speed, we can work out the distance by measuring the size of the enlargment of the object per certain time.

It is measure in astronomical unit (AU)
ex. The distance between Sun and Earth is 150 million km, 1 (AU)

How are the Distances between different objects in space measured?
they use light-years to determine the space between objects in space
Why is the safe cushion of space measured in seconds and not in feet or distance?
It is a lot easier to count seconds than to estimate distance.
What is The amount of space between two objects or places?
Distances used for measurments in space include the astronomical unit or AU (average distance from the Earth to the Sun), the parsec (the distance to the vertex of an angle of 1 second of arc subtending one AU) - often rendered more conveniently in kiloparsec Kpc, megaparsec Mpc, etc. - and the light year, or distance light travels in a vacuum in a duration of 1 Earth year. The parsec is about 3.26 light years.
What does distance mean in science?
Distance is the amount of space between two designated locations.
What refers to the amount of space between two points or places?
That's called the distance.
In distance in space between stars and earth measured in kilometres or light years?
in light years
What is the difference between the speed of light as measured on Earth and as measured on the International space station?
there is none.
What is distance of philosophy?
Distance is measured or measurement is distance.Distance exists in space and time.Time exists in space.Space is a created phenomena.Just as space in a jar there is space in between words.Time is supposed to travel within that space. Time is measured and so also the created space.
What is it called when you measure distance between stars?
usually the space is measured in light years
What is the total distance of earth?
"Distance" is defined between TWO objects, or points in space.
Name and explain the unit used to mesure distance in space?
Distances between earth-orbiting objects, and between those objects and the earth's surface,out to the natural moon: measured in miles or kilometers.Distances between major objects in the solar system, sun, planets, comets etc.:measured in miles, kilometers, and Astronomical Units (AU). The AU is the averagedistance between the earth and sun, roughly 93 million miles.Distances between the solar system and anything outside of it: measured in light-years.The LY is the distance light travels through space in one year, equal to about 63,200 AU,or 5.8787 x 1012 miles.
The distance between 2 point is called?
It is simply called the distance between the two points - simple as that. How that distance is measured will depend on the nature of the surface on which the two points are located as well as on the metric for measuring distance that is defined on that space.The common metric in Euclidean space is the Pythagorean distance while on the surface of a sphere (like the Earth, for example), distances are measured along the great arc.
What is the measurement used to measure distance in space?
Distance in space is measured in 'light years' or in 'scientific notation'
Why is the surface of the earth smooth when viewed from space?
Because the details on earth are diminished as the distance between the earth and the viewer increases.
What is the distance between Earth and the International Space Station?
On average, the ISS (International Space Station), is about 199 to 215 miles above the surface of the Earth.
How do you calculate speed and distance in space?
The answer depends on what information, if any, you have. If your question is in the context of space walks near earth-orbiting stations, you could have gyroscopes that measures your movement. Distance is easily measured, especially with laser range-finders, Change in distance is velocity and so on.
What planet has 8 rings that reach into space about the same distance as it is between the Earth and the Moon?
Saturn
