The Roman Pantheon is arguably one of the most well known pantheons. The Roman and Greek Pantheons are very much alike. They have very similar deities, where the only immediate visible difference is their name. The Roman pantheon is also well known for the fact that many of our planets are named after them. (Examples: Jupiter, Saturn, Mercury, Neptune, Mars, Venus, etc..) Some of the moons in the Milky Way Galaxy and some of the satellites we have sent out are also named after deities from the Roman pantheon.
The following is a list of some of the most popular Roman deities that may possibly be added into Smite later on: Jupiter, Saturn, Mercury, Mars, Venus, Diana, Minerva, Juno, Neptune, Cupid, Luna, Pluto, Uranus & Vulcan.
It is possible that the other popular deities will be added in the future.
