"This presents an opportunity for humans to return to deep space for the first time in 45 years."
The flight will take about a week to complete and will fly around the moon without touching down on its surface.
"[It] would rely on SpaceX's Falcon Heavy rocket, the massive engine that the company hopes to test for the first time this summer, and a Dragon 2 capsule," The Guardian reports.
The names of the first two travellers have not been released, says CNN, but they are likely to be "paying millions for the adventure".
Musk said the cost of the flight would be "comparable" to sending an astronaut to the International Space Station, for which Russia's space agency Roscosmos charges Nasa around $70m (£56m).
