Answer Wiki. If a rocket went straight up, it would either continue in that direction and leave Earth, or it would fall back down, depending on its velocity. Most rockets intend to enter orbit, which is an elliptical trajectory, and it's much more efficient to arc into this trajectory than to go straight up and then accelerate laterally.
No rocket has ever gone to the Sun. Of course it would depend on how fast it went too. Rockets do not all go the same speed. It is 93 million miles from the Earth to the Sun.So at a million miles an hour it would take 93 hours, but no rocket has ever gone that fast.f you could get a rocket to go 66,000 MPH, which is STILL faster than any rocket has even gone, that would cancel out the speed it started with on Earth due to the Earth orbiting the Sun and it would fall into the Sun due to the Sun's gravity.
