In astronomy I usually see Earth designated with a circled plus or cross. NASA says this is the Earth's astronomical symbol. Wikipedia tends to use it, for example designating the Earth–Moon distance by $\Delta_{\oplus L}$. But Wikipedia also says that the globus cruciger ♁ is used to symbolize Earth.

Does the latter find any usage in astronomy?

(The actual Unicode code point for the circled plus Earth symbol is U+1F728 but this does not render for me, so I used the graphically similar U+2295 instead.)

Yes, I don't know how common the globus cruciger is, but it is used at least here for the electron neutrino pp flux at Earth: NEUTRINO 2006: Proceedings of the XXIIth International Conference on Neutrino Physics and Astrophysics.
