Which statement is not true about the astronomical unit? a) au is the distance from the center of the earth to the center of the sun b) u is increased by 3,000,000 miles every 15 years c) the au is approximately 93,000,000 milesd) and u is equal to 0.1581 light years fast worth 10poinnts

B) AU is increased by 3,000,000 miles every 15 years

Explanation:

Statement B is wrong because the AU (Astronomical Unit, which is defined as the distance between the centre of the Sun and the centre of the Earth) is approximately constant.

To be more precise, the distance between the Earth and the Sun increases approximately by 15 cm every year. This means that after 15 years, the AU will be increased by

15 cm x 15 = 225 cm = 2.25 m

Which is totally different from 3,000,000 miles of statement B. Therefore, this statement is wrong.
