It's not as hot as you'd think. Solar panels (highly absorbing) reach slightly over the boiling point of water in direct sunlight. Metals work fine, so do a surprising number of composites and plastics.

* Aluminum, Magnesium, Titanium, Berylium

* Graphite/epoxy, Aramid/epoxy, Glass/epoxy

Reflective mylar.

Something with a black back to radiate the heat back out to space.

This is (very) stupid.

Mushroom. What other material would a parasol be?

i hear it's extremely cold out there

It is both incredibly hot due to solar radiation, and extremely cold, due to the lack of atmosphere to transfer heat.

The sun-side of this parasol will be all melty, while the shade side will be extraordinarily chilly. Whatever it is made of, will need to withstand that extreme thermal gradient.

If the temperature of the moon is anything to go by, it's hot but not too hot. According to NASA:

>Temperatures near the Moon's equator can spike to 250°F (121°C) in daylight, then plummet after nightfall to -208°F (-133°C).

Something like aluminum foil should work fine.

There's also the possibility of occasional space debris or solar flares striking the parasol

Very minor possibility though as any space debris that is not already in a semi-stable orbit would most likely have been filtered out by the planets before making it to any location inside of Earths Orbit, and a space parasol would be fairly small on an astronomical scale.

> What material would this have to be made of to not melt?

I would just use a giant array of solar PV panels as screen, then build a huge coil gun nearby and use all that energy to deflect potential dangerous asteroids by throwing them projectiles made of collected and recycled debris from decommissioned satellites.
