On February 6, 2018, a Tesla Roadster owned by Elon Musk was sent into space aboard SpaceX's Falcon Heavy rocket from the Kennedy Space Center in Florida. This event marked a unique moment in space exploration, as the car was placed into an elliptical orbit around the Sun, moving between the areas near Earth and Mars without stopping at either. The Roadster is now tracked like an asteroid, with its position recorded in NASA's JPL Horizons system under the designation -143205.
The Tesla Roadster's orbit takes it as far as 248.9 million kilometers from the Sun, reaching a distance of 1.664 astronomical units, which is slightly beyond the average distance of Mars from the Sun. In October 2020, the car made a notable close approach to Mars, moving at a relative speed of about 345 kilometers per hour while drifting away from the planet and toward Earth, which it was approximately 60 million kilometers from at the time.
Scientists estimate that the Roadster could continue its journey through the solar system for several hundred million years before eventually being either consumed by the Sun or ejected from the solar system, likely influenced by the gravitational pull of Jupiter. The Falcon Heavy launch, which was designed to test the rocket's capabilities, was a major success and helped validate the rocket's design, which is still used for important space missions today.
Now an artificial satellite of the Sun, the Tesla Roadster continues its silent journey through space, invisible to the naked eye but trackable using modern computational tools. Independent simulators allow anyone to follow the car's approximate real-time position, offering a glimpse into this unusual spacefaring artifact.
