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.
The distance between Earth and space is typically measured from the Earth's surface to the Kármán line, which is approximately 62 miles (100 kilometers) above sea level. This is where space officially begins and is commonly used as the boundary between the atmosphere and outer space.
On 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
We 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.
Using a technique called parallax
It is measure in astronomical unit (AU)
ex. The distance between Sun and Earth is 150 million km, 1 (AU)
The astronomical distances are measured in astronomical units, in which 1 astronomical unit = 149,598,000 km (the mean distance between the Earth and Sun).

What is a distance the length between two?
Distance is a measurement of the length between two points in space, typically measured in units such as meters or kilometers. It reflects the amount of space or separation between two objects or locations.
What is The amount of space between two objects or places?
The amount of space between two objects or places is known as distance. It is a measure of how far apart they are from each other. Distance can be measured in various units such as meters, kilometers, or miles.
What kind of quantity is distance?
Distance is a scalar quantity that represents the physical length between two points in space. It is typically measured in units such as meters or kilometers.
What type of quantity is distance?
Distance is a scalar quantity that measures the extent of space between two points. It is a physical quantity that is typically measured in units such as meters or kilometers.
What is ditance in physics?
Distance in physics refers to the amount of space between two points, measured along a straight line. It is a scalar quantity, meaning it has magnitude but no direction. Distance is commonly measured in meters (m) or kilometers (km).
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 a distance the length between two?
Distance is a measurement of the length between two points in space, typically measured in units such as meters or kilometers. It reflects the amount of space or separation between two objects or locations.
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.
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.
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 distance between earth and space station?
The distance between Earth and the International Space Station (ISS) varies as it orbits the Earth at an average altitude of about 420 kilometers (260 miles). The distance can range from around 370 kilometers to 460 kilometers depending on the station's orbit.
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 amount of space between two objects or places?
The amount of space between two objects or places is known as distance. It is a measure of how far apart they are from each other. Distance can be measured in various units such as meters, kilometers, or miles.
