Starman — the dummy razz a cherry red - red Tesla Roadster through distance — has made his closest approaching ever to Mars .
That electric exchangeable with its mannequin passenger run off to the top of a Falcon Heavy skyrocket as a stunt during theSpaceXrocket ’s first test launch Feb , 6 , 2018 . ( It ’s common for exam launch to let in lowering consignment , but they ’re ordinarily more boring than cerise - red sportscars . ) Two class after , the Falcon Heavy upper stage and the vehicle at its tip are making their 2d tripper around the sunlight . Jonathan McDowell , a Harvard astrophysicist who tail space physical object as a side project , found that Starman pass 4.6 million miles ( 7.4 million kilometers ) from Mars at 2:25 a.m. EDT Oct. 7 . That ’s about 19 sentence the distance fromEarthto the synodic month , and 35 metre closer than anyone on Earth has suffer to Mars .
Starman sent pictures home before leaving Earth orbit.
( The closelipped recent approach between the two planets was 34.8 million miles ( 56 million klick ) in 2003 , according toWorld Atlas , though the planets are often hundreds of one thousand thousand of miles aside . )

No one can see the Falcon Heavy upper degree at its current distance . And the unusual , beautiful images it once beamed home to Earth have long since quit . But orbits over periods of a few years are somewhat straightforward to predict , and McDowell used datum about how the rocket was move when it left Earth’sgravitybehind to nail its recent movements .
The Roadster - carry rocket phase is on an asymmetrical orbital course that takes it as far as 1.66 times Earth ’s distance from the sun at one death of its trek — out beyond the orbit of Mars — and then back within Earth ’s orbit at the other end , 0.99 fourth dimension Earth ’s distance from the sun .

Last time Starman circled the sun , McDowell say , it crossed Mars ' range while the Red Planet was quite far forth . But this prison term the crossing lined up with a middling unaired approach — though still not close enough to feel a strong tug of Martian gravity .

At this point , if you were to go look at the Roadster , it likely would look somewhat different . AsLive Science reported in 2018 , the abrasive solarradiationenvironment between the planet would probably have wrecked all the exposed constituent stuff ( red blusher , prophylactic tyre , leather seats and the like ) , breaking thecarbon bondsthat hold them together . And without Earth ’s protective air and magnetised shielding , even the robust plastics in the windscreen and carbon character materials would start to decompose . Over the row of decades or 100 , the car should be reduced to its aluminum chassis and sturdiest glass division — assuming none of them get destroyed in impacts with overhaul space rocks .
