Several methods are used, depending on the distances involved; most methods involve some sort of "standard candle".I suggest checking the Wikipedia article on "Cosmic distance ladder" for more details.
Distance in space is measured in 'light years' or in 'scientific notation'
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.
usually the space is measured in light years
It is a lot easier to count seconds than to estimate distance.
in light years
There are two main units of distance used for measuring space distances, they are solar units and light years
Distance from the Equator is measured in Latitude .
In Light-Year(s) ; see related link below .
Distance is measured in kilometres, such as the distance between two towns, or the distance from the Earth to the Moon.
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.
Distance can be measured in metres.
What is the greek word for the distance measured by 200 yards
