  We consider the survivability of planetary systems in the globular cluster 47
Tucanae. We compute the cross sections for the breakup of planetary systems via
encounters with single stars and binaries. We also compute the cross sections
to leave planets on eccentric orbits. We find that wider planetary systems (d >
0.3 AU) are likely to be broken up in the central regions of 47 Tucanae (within
the half-mass radius of the cluster). However tighter systems, and those in
less-dense regions may survive. Tight systems will certainly survive in
less-dense clusters where subsequent surveys should be conducted.
