KIDS TRIVIA

Detailed explanation-1: -Space debris can be as large as an inactive satellite, similar to the size of a car, or as small as a flake of paint. The real danger is the speed at which these objects move, more than 28, 000 kilometres per hour, which turns them into real projectiles.

Detailed explanation-2: -Based on statistical models produced by ESA’s space debris office, it is estimated that there are 36, 500 objects larger than 10cm, 1 million objects between 1-10cm, and an extraordinary 130 million objects between 1mm to 1cm.

Detailed explanation-3: -There’s a lot of space junk up there orbiting the planet, but what effect is it having? There is no direct effect, although the density of space debris is now so great that astronomical observations are often degraded by it. The main problem is that of collisions with operational spacecraft.
