Answer:
Astronomers use radar measurements, telemetry and exploration of solar system to get precise measurement of astronomical units.
Astronomers use parallax techniques. They measure the distance between the Earth and solar planets. Astronomers use parallax techniques to conduct parallax measurements which gave them accurate and precise values of the length of astronomical units
Explanation:
Astronomical unit is a unit length which is the average distance between the Earth and the sun which is about 150 millions kilometers.
Astronomers use radar measurements, telemetry and exploration of solar system to get precise measurement of astronomical units.
Astronomers use parallax techniques. They measure the distance between the Earth and solar planets. Astronomers use parallax techniques to conduct parallax measurements which gave them accurate and precise values of the length of astronomical units.
