Here is an informative chart that shows how much garbage floats around in space. I found this chart in Bloomberg Businessweek of December 16, 2019 on page 35:
1mm is about the size of a pinhead and 1cm is about the size of a large blueberry.
According to the European Space Agency, as of January 2018, there are about 29,000 objects larger than 10 centimeters, around 750,000 objects that range between 1 cm to 10 cm and about 166 million objects between 1 millimeter to 1 cm in size (those are the little dots in the chart above, where each dot represents 3,000 objects). Each one of those is big enough to easily puncture a space capsule.
