Liang, Bin; Dong, Huining Study on expansion of the solar system. (English) Zbl 1078.85003 J. Sichuan Norm. Univ., Nat. Sci. 28, No. 1, 80-83 (2005). Summary: With the decrease of the solar mass, namely, with the decrease of the solar gravitational field, the orbital scope of the planet extends, and the form of the elliptic orbit may become flatter. The farther the planet is from the sun, the more obvious the orbital variation of the planet is. The solar system is expanding very slowly and evenly, at the same time, the energy of the planet is increasing.
