Where is the roadster going?
Starman was said to be on a 400-million-kilometer trip into Mars orbit, powered by the main module that parted shortly after Falcon Heavy's launch.
However, in a slight hiccup, Elon Musk admitted that SpaceX had surpassed Falcon Heavy's third booster burn, which sent Starman further into the solar system than originally planned.
The new orbit will send the Roadster on a journey into the asteroid belt between Mars and Jupiter.
What will happen to it?
The main force that will rip the car through space for hundreds of millions of years is radiation.
This concerns in particular the plastic and carbon fiber frame.
"[Those materials] consist mainly of carbon-carbon bonds and carbon-hydrogen bonds, "said Dr. William Carroll, a chemist at Indiana University, told Live Science.

On Earth, we are protected by a strong magnetic field and a strong atmosphere that protects us from the sun's worst radiation and cosmic rays.
Radiation in space causes these bonds to break, eventually destroying the car.
"If you cut something with a knife, you end up cutting some chemical compounds," Dr. Carroll.
"All organic matter will be affected by the different types of radiation that you will encounter there," he said.
How long it will take?
"I would not give them these organic substances in this environment for a year," Dr. Carroll.
The well-secured inorganic materials, such as the aluminum frame and the interior metals, would last longer, so that they could still be seen in at least a million years.
However, it is unlikely that any collisions with micrometeorites and other space debris will be avoided in the meantime.
Before the start, Musk said there was a chance the car could hit Mars. On the new way, it is not clear now whether the car might hit another space object.
