We would start a million or billion or trillion year journey to find a new star in whatever direction the earth happened to be headed at the instant the sun went AWOL. The sun doesn't actually have to vanish for this to happend. If some other star got too close it would counteract the sun's gravity and send us on our way.

Kinda depends on how it vanishes. It is going to implode and suck us in? We stay in orbit because our foward motion is equal to the pull of gravity from the sun-an equilbrium all orbiting things have. Without the sun there would be no gravity and our forward motion would propel us out into space.

Earth would stop orbiting the nonexistent sun and assume a straight line trajectory. The velocity would remain at about 18 miles per second.

Who cares about the orbit. Nobody will live to see what is happening because life without Sun is not possible.

about 8 minutes after the sun vanished, earth would go in a straight line until perturbed by some other massive object.

We would all freeze to death before we had a chance to worry about the orbit of the Earth.

If no sun where is it going to orbit
?

I believe (not sure) that inertia would keep the Earth traveling in its current orbit, since there is no friction in space to slow it down. The other planets might cause that orbit to change slowly over the course of centuries, and it is possible that the Earth would collide with the Moon without the influence of the Sun's gravitational pull.
It wouldn't matter to humanity, though; we would all freeze to death within a week or so.

instead of traveling in an elliptical path we would travel in a straight line through space.

the orbit wouldnt matter we would all die of an ice age
