Get a stick of bamboo or other light wood and move it quickly to and fro in front of the mic. Swish it back and forth as fast as you can without hitting the mic or yourself. You will probably need to speed up and pitch-shift the audio once it’s in your DAW, but that should give you the sound of the star flying through the air.
For the impact, take a hatchet or sharp knife and strike into several objects: A fruit (I used an apple), a piece of wood (Hitting a real tree or a stump is better, but you may have to deal with background noise), and concrete (to get a metallic ring).
Layer these to make a strong sounding impact.
