Suppose the energy density of the cosmological constant is equal to the present critical density En = Ec0 = 4870MEVM3. What is the total energy of the cosmological constant within a sphere 1AU in radius?What is the rest energy of the Sun (Eo = Moc2)? Comparing these two numbers, do you expect the cosmological constant to have a significant effect on the motion of planets within the solar system?
