The Astronomical unit is used to measure the large distances in our solar system. It is roughly the average distance between the Earth and the Sun.

Any ruler that has a division in centimeters. For somewhat longer distances you measure in meters. To know how long that is, take a piece of rope between your fingertips and measure the distance from the tip of those fingers to the outside edge of your other shoulder. If you're about 12 years or older, that distance is a meter.
Kilometers are more likely to be used to measure the distance between two places, rather than the size of objects, since in our normal experience, objects are more likely to be measured by meters or centimeters rather than by kilometers. However, the diameter of planets and their moons, or of the sun or stars, can be measured in kilometers.
Mass can either be measured in grams, kilograms, pounds But the SI unit of mass is kilograms
When describing distances on the scale of our solar system, conventional units of measure are not conventially sized. Miles are so small and the large things are lightyears, to permit simply compared numbers. For example, between the sun and the earth are 93,000,000 miles; Between the sun and Pluto is about 3,700,000,000 miles away. However, comparing those two numbers it has difficulties to see that Pluto is about 40 times.
it is light years. And miles are to short.
Distances between celestial bodies are typically measured in astronomical units (AU) for objects within our solar system, and in light-years for objects outside our solar system. Astronomers use techniques like parallax, radar ranging, and spectroscopy to measure these distances accurately. Additionally, tools like the Hubble Space Telescope help provide precise measurements of distances to objects in space.
In the solar system, the distances between planets are much larger compared to the size of the planets themselves. In the universe, the distances between galaxies are also vast compared to the sizes of the galaxies.
meters, feet, and even miles are way too small to measure distances in space. astronomical units are mostly used to measure distances in our solar system. light years are used to measure the distances of things further away from our solar system.
The orbit and the roll lover cover.
Distances in space are measured using a variety of methods, such as parallax for nearby stars, radar for planets in our solar system, and redshift for galaxies and other objects in the universe. These measurements help astronomers understand the scale of the universe and the vast distances between objects in space.
Light years, parsecs, and kiloparsecs. Light years and parsecs are used to measure distances between neighbouring star system's, kiloparsecs are used to measure distances within a galaxy.
Astronomical units (AU) are based on the average distance between the Earth and the Sun, which is about 93 million miles. This unit is not practical for measuring distances beyond our solar system due to the vast scales involved. For interstellar or intergalactic distances, astronomers use light-years or parsecs, which are much larger units that can accurately represent these immense distances. Additionally, the use of AU outside the solar system would lead to confusion and lack of precision in measurements.
A light year is the distance that light travels in one year, equal to about 9.5 trillion kilometers. It is used to measure vast distances in space. An astronomical unit (AU) is the average distance between the Earth and the Sun, about 150 million kilometers. It is commonly used to measure distances within our solar system.
A centimetre is one one hundredth of a metre.
Millimeters are a unit of measurement in the metric system, equal to one thousandth of a meter. It is commonly used to measure small distances or the dimensions of objects.
Miles, yards and feet were once the main measurements to measure distances between towns, etc. Nowadays, due to changing over to a decimal system, kilometres and metres are usually used.
