Mercury is 5.8 times 10^7 from the sun. Neptune is 4.5 times 10^10 km from the sun. How much further is Neptune from the sun than Mercury?

To find out how much further Neptune is from the sun than Mercury, we need to subtract the distance of Mercury from the sun from the distance of Neptune from the sun.

Neptune is 4.5 * 10^10 km from the sun
Mercury is 5.8 * 10^7 km from the sun

4.5 * 10^10 km - 5.8 * 10^7 km
= 4.5 * 10^10 km - 0.58 * 10^8 km
= 4.5 * 10^10 km - 5.8 * 10^7 km
= 44500000000 km - 58000000 km
= 44442000000 km

Therefore, Neptune is 44,442,000,000 km (or 4.44 x 10^10 km) further from the sun than Mercury.
