1. Discuss the advantages and disadvantages of measuring stellar parallax from a space telescope in a large solar orbit, say, at the distance of Jupiter from the Sun.

2. All stellar parallax angles, p, were observed to be increasing? What would that imply about the motions of stars? Is there another observational technique that could be used to confirm this motion?
