That's a quite a difference from what we were told. I wonder why that is?

For the simple mortals. How far is going ? asteroid belt?

No. Just out to the orbit of Mars. Elon's earlier orbit was wrong (as we had already suspected).

Early orbital estimations always have a large error, as they're based on very few data points rather close together. I think may have just "burned until there was nothing left in the tank" rather than a precision burn.

How many days will it take the roadster to go around the sun? The roadster year:-)

Awesome! Thanks. I've updated the REBOUND simulation. Quite the difference from the orbit described in 's tweet...

At what point would you be able to calculate the exact number of days?

with 0.99 and 1.71 AU I get 1.5686 years.... kepler's 3rd law rules :) all about accuracy of data

I'd read it'd have an elliptical orbit around both Earth and Mars - is that an oversimplification?

It has an elliptical orbit around the Sun, which crosses the orbits of Earth and Mars.

Really not even close to the asteroid belt. It will make it just past Mars orbit.....right??

NASA's LSP performance calculator puts the maximum payload that FH w/ 1st stage recovery can lift to this orbit at 4000 kg.

Copy that. To what extent should orbital paths be licensed? Is space navigation akin to Freedom of the Seas? Could society impose eminent domain at some future date? Could someone or a group own an orbit & have a right to defend it? Where does Musk stand on this legally?

Here's a simulation using Jonathan's numbers of 0.99 x 1.71 x 1.1 deg inclination
