Suppose the energy density of the cosmological constant is equal to the present critical density εΛ=εc,0=4870 MeV m−3. What is the total energy of the cosmological constant within a sphere 1 AU in radius? What is the rest energy of the Sun (E⊙=M⊙c2)? Comparing these two numbers, do you expect the cosmological constant to have a significant effect on the motion of planets within the solar system?
