Question: What Planets Have Been Discovered Since October 1995?...And.....? Compare them to what we know about the planets including our own.

Answer: Since 1995, scientists have discovered more than 70 new planets and planetary systems, but most don't resemble our solar system. Instead, scientists have been surprised to find gas giants orbiting very close to their host stars. Theorists speculate that some of these large planets may have migrated inward because of gravitational interactions with the protoplanetary disk.
