**drwls**, Tuesday, June 16, 2009 at 6:18amThe ratio of orbit semimajor axis lengths is

a2/a1 = 1.524*10^8/1.50*10^8 = 1.016

For the earth, the period is P1 = 365.25 days.

Use Kepler's third law to get the period for the artificial planet.

a^3/P^2 = constant

P2/P1 = (a2/a1)^3/2 = 1.0241

P2 = 374 days
