On February 6, 2018, SpaceX made history by launching the Falcon Heavy rocket, the most powerful operational rocket in the world, into space. This groundbreaking mission not only marked a significant milestone in the development of space technology but also sparked widespread fascination with the idea of exploring Mars. A key aspect of this mission was the payload it carried: Elon Musk’s personal Tesla Roadster, with a dummy driver named Starman at the wheel. As Starman embarks on its journey through the vast expanse of space, many are left wondering: how close will Starman get to Mars?
Introduction to Starman and the Falcon Heavy Mission
The Falcon Heavy is a reusable heavy-lift launch vehicle designed and manufactured by SpaceX. With the ability to lift nearly 64 metric tons (141,000 lb) to low Earth orbit, it is the most capable rocket currently in operation. The Tesla Roadster, a sports car owned by Elon Musk, was chosen as the dummy payload for the Falcon Heavy’s maiden flight. The Roadster was placed in an elliptical orbit around the Sun, with its closest approach (perihelion) at about 0.99 astronomical units (AU) from the Sun and its farthest distance (aphelion) at about 1.67 AU from the Sun. One astronomical unit is the average distance between the Earth and the Sun, which is approximately 93 million miles or 149.6 million kilometers.
Calculating the Trajectory of Starman
To understand how close Starman will get to Mars, we must first comprehend the trajectory it is on. The orbit of the Tesla Roadster, with Starman as its passenger, is not a simple circular path around the Sun but an elliptical one that takes it through the inner solar system. The rocket’s upper stage was shut down after placing the car into a temporary Earth orbit, and then a final burn was used to send the vehicle out of Earth’s orbit and into an orbit around the Sun.
The spacecraft does not have an engine or any means of propulsion aside from the initial thrust provided by the Falcon Heavy, so its path is determined by gravitational influences and the initial velocity imparted to it. The car will make its closest approach to the Sun (perihelion) within a few months after launch and then travel outward, moving further away from the Sun until it reaches its aphelion. This orbit is such that Starman will periodically come close to Mars but never actually land on the planet.
Understanding the Gravitational Influence of the Solar System
The trajectory of Starman is influenced by the gravitational pull of the planets it passes near, particularly the Earth and Mars. When the Roadster was launched, it was initially in an Earth-centered orbit. After the final burn, it transitioned into a heliocentric orbit, meaning its orbit is centered around the Sun. The gravitational influences of other celestial bodies, though weaker compared to the Sun, can still affect the car’s path. However, given the vast distances involved and the lack of significant gravitational interactions, Starman’s path is not expected to deviate dramatically from its current trajectory.
Approaching Mars: The Closest Encounter
The question on everyone’s mind is how close Starman will get to Mars. According to SpaceX and Elon Musk, the Tesla Roadster is expected to pass within a few million miles of Mars. This distance is incredibly close in astronomical terms, yet vastly too far for the car to be captured by Mars’ gravity or to land on its surface. The closest approach, or periareion, in relation to Mars is estimated to occur about 6 months after launch. However, the exact distance and timing can vary due to the complexities of orbital mechanics and the gravitational influences of other bodies in the solar system.
Predicting Future Encounters
In the coming years and decades, Starman will continue on its orbit around the Sun, occasionally passing close to both Earth and Mars. Each time it approaches these planets, the possibility exists for its orbit to be slightly altered due to gravitational interactions, although these effects are expected to be minimal. Over millions of years, the cumulative effects of gravitational influences could potentially alter Starman’s orbit in more significant ways, but predicting such changes with certainty is complex due to the chaotic nature of the solar system’s dynamics.
Long-Term Fate of Starman
The long-term fate of Starman and the Tesla Roadster is a topic of ongoing speculation. Elon Musk has suggested that the car could remain in its current orbit for millions of years, potentially becoming a time capsule of sorts, representing humanity’s technological achievements in the early 21st century. However, there are also possibilities that, over a very long period, Starman could be ejected from the solar system, collide with another celestial body, or even be captured by the gravity of a planet, although these outcomes are highly speculative and dependent on factors such as encounters with asteroids or comets.
Conclusion: The Significance of Starman’s Journey
The journey of Starman, aboard the Tesla Roadster, marks an exciting chapter in space exploration and technology. While the primary mission was to test the capabilities of the Falcon Heavy rocket, the inclusion of a Tesla with a spacesuit-clad dummy named Starman has captured the imagination of people worldwide.

How will Starman’s trajectory take it close to Mars?
Starman’s trajectory will take it close to Mars due to the precision with which the Falcon Heavy rocket was launched. The rocket’s guidance system ensured that the Tesla Roadster was placed into an elliptical orbit around the Sun, with a perihelion (closest point to the Sun) of approximately 0.99 astronomical units (AU) and an aphelion (farthest point from the Sun) of approximately 1.67 AU. This orbit will take Starman within approximately 4.8 million miles of Mars, which is a relatively close approach considering the vast distances between objects in our solar system.
As Starman approaches Mars, it will be traveling at a speed of approximately 25,000 miles per hour, which is incredibly fast by astronomical standards. Despite its high speed, however, Starman will not be entering into orbit around Mars or landing on the planet’s surface. Instead, it will simply fly by Mars, providing a unique opportunity for scientists to study the Red Planet from a unique perspective. The close approach will also provide valuable data on the performance of the Falcon Heavy rocket and the Tesla Roadster, which will be used to inform future missions to Mars and other destinations in the solar system.
What will happen to Starman after it passes Mars?
After Starman passes Mars, it will continue on its elliptical orbit around the Sun, eventually becoming a permanent resident of the outer solar system. The Tesla Roadster will not be entering into orbit around any other planets or celestial bodies, and it will not be intentionally crash-landed on any planetary surfaces. Instead, it will simply drift through space, becoming a small but intriguing part of the solar system’s vast and complex landscape. Over time, Starman’s orbit may be perturbed by the gravitational influence of nearby planets, but for the foreseeable future, it will remain a stable and inert object in the outer solar system.
The long-term fate of Starman is uncertain, but it is likely that the Tesla Roadster will remain in orbit around the Sun for millions or even billions of years. Eventually, the spacecraft may be ejected from the solar system altogether, becoming an interstellar object that drifts through the vast expanse of interstellar space. Alternatively, it may be perturbed into a collision course with a nearby planet or other celestial body, although this is highly unlikely given the vast distances and timescales involved. Whatever its ultimate fate, Starman will remain an important milestone in the development of SpaceX’s ambitions for space exploration, and a testament to the ingenuity and creativity of the company’s engineers and scientists.
