What If Earth Went Rogue?

This sudden shift in Earth's gravity would make our planet break away from orbiting the Sun. And now, for the first time in our planet's history, we would be drifting through space without any direction. How fast would Earth travel? Could we survive the extreme temperatures of space? And could the Earth fly through the asteroid belt?
