Is osmium safe to touch?

Osmium tetroxide is highly volatile and penetrates skin readily, and is very toxic by inhalation, ingestion, and skin contact.

Airborne low concentrations of osmium tetroxide vapor can cause lung congestion and skin or eye damage, and should therefore be used in a fume hood..

How heavy is the moon?

The moon’s mass is 7.35 x 1022 kg, about 1.2 percent of Earth’s mass. Put another way, Earth weighs 81 times more than the moon. The moon’s density is 3.34 grams per cubic centimeter (3.34 g/cm3). That is about 60 percent of Earth’s density.
