Lightyears
Two planets are at their greatest separation when they are on opposite sides of the Sun. When a planet is at its greatest separation from the Earth the planet is said to be at superior conjunction. It cannot be seen until it has separated out from the Sun, which usually takes a few weeks at least.
Distance at galactic scales is usually measured in terms of lightyears. Distance at cosmological scales may also be put in terms of Hubble red-shift factors.
The unit of measurement for speed is a fixed amount distance divided by a fixed amount of time. i.e.: Miles/Hour, Kilometers/Second, Meters/Hour, inches/day Currently in the US, milers/hour or "mph" is a standard for motor vehicles. It is kilometers/hour, or "kph" other countries. There might be some confusion with the above and the word "lightyears." 1 lightyear designates a distance, the distance light travels in 1 year through a vacuum. Some may confuse this as speed, when it is actually a measurement of distance.
Kilometer Converter Design a modular program that asks the user to enter a distance in kilometers, and then converts that distance to milies. The conversion formula is as follows: Miles= Kilometers X 0.6214
8 light years = 75685843780650 kilometers
The stars at the two ends, Alnitak and Mintaka are at a distance of 387 and 380 parces (1262 and 1239 lightyears) respectively. Due to the relatively small angular separation, the distance between the stars is approx 7 parsecs = 23 lightyears.
Two processes are separated by space or distance.
The position of zero force if positive and negative charges are separated by a distance would be at half of the separation distance.
Lightyear isn't about time, it's distance. One lightyear is ten trillion kilometers.
about 4 lightyears
100,000 lightyears.
Lightyears. The distance between the Sun and Earth is 1.49 lightyears (149 000 000 km)
The distance is 41 parsecs (approx 134 lightyears).
about 26000 lightyears
it is 4.24 lightyears away
