Six years ago, Elon Musk captured the world’s imagination by launching a Tesla Roadster into space. This audacious feat saw the car, with a dummy driver named Starman, take off on a SpaceX Falcon Heavy rocket in February 2018. Since then, the Roadster has orbited the sun four times, covering vast distances in the solar system. But could it ever return to Earth? Recent studies suggest that while the possibility exists, it’s a long-term prospect.
The website whereisroadster.com has been diligently tracking the car’s journey through space. As of now, the Tesla is approximately 82,283,753 miles away from Earth, traveling at a speed of 29,340 mph. The website’s updates have sparked curiosity and speculation about the car’s potential to make a return journey to Earth.
Researchers have approached this question by comparing the Roadster’s orbit to that of Near-Earth Asteroids (NEAs). In a study published in the journal Aerospace, scientists explored the dynamics of the Tesla’s trajectory. They noted that NEAs typically reach their orbits from the main asteroid belt via strong resonances, often leading them to plunge into the sun. The chances of such an asteroid hitting a planet are quite low, estimated at around 2%.
“The initial Tesla orbit grazes that of the Earth, so one might expect an initial period with enhanced collision probabilities with the Earth before it is randomized onto a more NEA-like trajectory,” the study states. This unique orbital path implies a higher initial risk of collision compared to typical asteroids.

However, the Tesla Roadster follows a different path. Its initial orbit grazes that of Earth, suggesting a period of enhanced collision probabilities before it potentially adopts a more NEA-like trajectory. This unique orbit means the Roadster’s journey is less predictable, raising intriguing questions about its future encounters with Earth or other terrestrial planets.
According to the research, the Tesla Roadster is expected to come within 3.1 million miles of Earth in 2047. While this distance might seem vast, it’s relatively close in astronomical terms. The researchers also considered longer timescales, estimating a 22% chance of the Roadster colliding with Earth over millions of years. This extended timeline suggests that any potential impact is far beyond our lifetimes.
While the idea of a space-faring Tesla returning to Earth is intriguing, several factors could alter its fate. The vehicle could collide with other space debris or be subjected to intense radiation, leading to its disintegration. Additionally, gravitational interactions with other celestial bodies could change its trajectory.
The possibility of the Tesla already being destroyed by a meteoroid or eroded by space radiation is also considered. If Starman and the Roadster are still intact, they may continue to drift through space for millions of years, adding a fascinating chapter to the story of human space exploration.
