Anewly discovered solar system is found 600 billion kilometers from the sun. how many au

1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=149597870.7 kiometers

1 billion=1,000,000,000
600 billion=600,000,000,000


x times 1AU=600,000,000,000
x times 149597870.7=600,000,000,000
solve for x
divide both sides by 149597870.7
x=4010.75
so aprox 4011 AU's

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
