Normally in Astronomical Units (AU) which is the average distance from the earth to the sun.
I think it is in Light years. But it depends if it the planet is closer then kilometers.
astronomical units
Inside our Solar System distances are measured in Astronomical Units (AU) which is the average distance from the Earth to the Sun, or about 93 million miles. Jupiter is about 5.5 AU distance from the sun or around 500 million miles. Distances outside our Solar System are usually measured in Light Years.
Any distances between two points outside the solar system, or betweenanything inside the solar system and anything outside it, are.(With the exception of the distances now being estimated between exoplanetsand their respective host-stars.)
the distance is measured in LIGHTYEARS.
You don't, miles are not a unit in the metric system. All distances are measured in metres. Prefixes are used for multiples or fractions of a metre. Distances that used to be measured in miles would, today, be measured in kilometres.
The distance between planets are measured in millions of kilometers while the distance between solar systems are measured in light years while the galxies and the universe are measured in AU (astronautical units)
in the solar system, distances are measured in AU's which stand for atronomical units.

No. Short distances (the width of a planet) are measured in kilometers. Distances from one place to another in our solar system are measured in Astronomical Units (AU), one AU being 93 million miles. Longer distances outside our solar system are popularly measured in light years, Alpha Centauri is 4.2 light years away, for example, but note I said "popularly". Astronomers use the term "parsecs" when speaking of interstellar distances (one parsec is 3.26 light years).

There are two main units of distance used for measuring space distances, they are solar units and light years
Any distance can be measured by any unit. It doesn't make a lot of sense to measure distances in light years, when it only takes light a few hours to make the journey within our solar system. Light goes from the Sun to Pluto in about 5.5 hours. Which is 0.00062 years, the assoicated distance being 0.00062 light years.
Interplanetary distances are measured in either kilometers or in miles. For the distant planets, some measures are measured in Astronomical Units, where one AU is the distance between the Sun and the Earth. So, 1 AU = 93,000,000 miles.
measuring distances in the solar system.
In the inner solar system, at distances of less than 5 AU from the Sun.
the solar system is measured in what are known as light years
