Question

Ganymede's orbital semi-major axis is ?

Ganymede is one of Jupiter's large regular moons. It orbits Jupiter at a distance (semi-major axis) of 1.07 x 10^6km with an orbital period of 7.16 days.

answer in scientific notation
____x10^---au

Answer 1

Ganymede's orbital semi-major axis is approximately 0.00715436242 au. In scientific notation, this is 7.15436242 x 10^-3 au.

Step-by-step explanation:

Ganymede's orbital semi-major axis is 1.07 x 10^6 km.

To express this value in scientific notation with astronomical units (au), we need to convert kilometers to astronomical units.

1 astronomical unit (au) is approximately equal to the average distance from the Earth to the Sun, which is about 149.6 million kilometers.

To convert from kilometers to astronomical units, divide the distance in kilometers by the conversion factor of 149.6 million kilometers.

1.07 x 10^6 km / (149.6 x 10^6 km) = 0.00715436242
