Very Large Next Extent

Hey Guys,
I ran the following query on one of my instances and I got the following results. I have a table with a next extent of 52428800 which is really very big. What do I do about this as export/import is not an option for this table (9 million rows ) and always being written to and other application constraints. Any hints , suggestions, experiences, comments welcome.

								Thank you.
