Why is the unit of measurement used for the distances of planets from the Sun different from the unit used for their sizes? The planets are spaced out unevenly which is called the inner solar system. In the outer solar system, the planets are more spread out.

Why are different units of measurement used for distances in space?
Astronomers use many of the same units of measurement as other scientists. They often use meters for length, kilograms for mass, and seconds for time. However, the distances and sizes in the universe can be so big, that astronomers have invented more units to describe distance.
What units are used to measure the distance from a planet to the Sun?
astronomical unit (AU, or au), a unit of length effectively equal to the average, or mean, distance between Earth and the Sun, defined as 149,597,870.7 km (92,955,807.3 miles).
Why do we measure some distances in astronomy in light years and some in astronomical units?
We added a new measurement the Astronomical Unit (AU) which is based on the average distance between the Earth and the Sun. This unit is good for measuring the distances between planets. ... Hence the light year is a convenient and manageable unit of distance for measuring the distance between objects in space.
What is the unit used to measure the distance in space?
To measure the distance of a star, astronomers use a baseline of 1 astronomical unit (AU), which is the average distance between Earth and the sun, about 93 million miles (150 million kilometers). They also measure small angles in arcseconds, which are tiny fractions of a degree on the night sky.
What units of measurement do we use to measure distances in space?
Because space is so big, many astronomers do not like to say how far away things are using miles or kilometers. Instead, we use a measurement that we call a parsec. Remember Alpha Centauri, the closest star? It is 1.347 parsecs, or 41,560,000,000,000 (or 41.56 trillion) kilometers away.
What unit of measurement would be the most appropriate to use to indicate distances between planets?
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars. It is also a fundamental component in the definition of another unit of astronomical length, the parsec.
What would you use to measure the distance between Earth and Saturn?
We can determine the distance between Earth and Saturn by knowing the distance from the sun to each planet. Earth is 92,957,130 miles (or 149,600,000 kilometers) from the sun.
What unit of measurement would you use to measure between Earth and Pluto why would you use this unit?
One Astronomical Unit is defined as the distance between the earth and the sun. Mars is about 1.52 AU from the sun. Pluto is about 40 AU from the sun. This unit is used because many distance calculations rely on parallax measurements.
Why do we measure distance in light-years?
The main reason for using light years, however, is because the distances we deal with in space are immense. If we stick to miles or kilometers we quickly run into unwieldy numbers just measuring the distance to the nearest star: a dim red dwarf called Proxima Centauri that sits a mere 24,000,000,000,000 miles away!
Why is space distance measured in light-years?
A light-year is a measurement of distance in space. The astronomical distances are measured in light-years because, the speed of light is constant throughout the universe and is known to high precision.
Why is a light-year a unit of distance?
Answer: A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second.
