Happy Perihelion Day

Just a special wish for a happy day for all astronomers on January 4th.
Given the success so far from Stardust and Spirit, looks promising already.

Incidentally, when interviewing applicants for university places to do
astronomy, I find that asking a question about the explanation of the
seasons reveals that some still think perihelion is on June 21st.

There is compensation, from those who can give a coherent and correct
explanation.
