When exploring a small planet with a radius of $569$km and a mass of $6\mathrm{.}181020$kg$,$ a small spacecraft with a mass of $7670$kg is placed in an elliptical orbit around it$.$ When the spacecraft is at a distance of $1230$km from the center of mass of the small planet, it has an orbital speed of $479$m$/$s

What is the orbital speed, in meters per second, when the spacecraft is at a distance of $9670$km from the small planet?
