Many of the objects have since burned up in the atmosphere and currently there are just over 17,000 trackable objects in orbit. Less than 10% of these active satellites. This visualisation, created by Dr Stuart Grey, lecturer at University College London, shows how the amount of space debris has changed since the dawn of the space age. The tracking data covers objects over 10cm in size and is supplied by https://www.space-track.org If you are interested in our orbital environment, please subscribe to Watch this Space!

Top comments AlTerkait AlTerkait7 months ago It looks like so much because the scaling is waaaay off. Sure, that's a lot of debris, but realistically, the distance between them is very vast. Reply 27 View all 3 replies hoogreg hoogreg4 months ago Yea well, if I were TO SCALE you'd be out of here so fast I tell you what. Reply Anthony C Anthony C1 month ago While the scale is big here the real problem is the sheer volume of debris being tracked since 1957. It basicly means if we dont start to find a way to clear/limit this effect as we could render our options when it comes to orbital craft/assembly etc. Reply JUanHernandezism JUanHernandezism3 months ago year 2185 on a colonized Mars. Son: Daddy, what was earth like in 2016? Father: Earth was beautiful. It had junk everywhere, in piles at a dump, the ocean, and we even had junk rings around the planet!

Reply 2 T38 Talon T38 Talon6 months ago At some point we won't be able to launch and make it through 'the cloud'. We're at the advent of micro-sats so this will only get worse, quickly. I can see a cascade/domino type collision in our future with stuff raining down like a meteor shower...

Most of them are not bigger than a car. If you see a car from miles and miles away, you won't be able to actually "see" them. They are too far away and too little to be visible, but that doesn't mean that we don't have a future problem in our hands.

Reply 1 rollvideo rollvideo4 months ago (edited) In other words: If a satellite is placed in a geo-stationary orbit (staying above the same point on Earth) it must be placed up to 22000kms out into orbit. If a satellite is much lower (like many of them, including the International Space Station) it must travel faster to maintain altitude because of Earth's gravitational pull. Because of this, low-altitude satellites cannot maintain a hovering position. In the early days spy satellites would only get a few minutes to view a particular spot on earth before vision would be lost as it sped away on its constant trip around the planet. With better cameras and lenses this limitation is becoming much less of an issue. Read more Reply 1 lettucepicker lettucepicker4 months ago Amen to space exploration..
