@Reed Julius I tried that service and it downloaded a key-logger virus and tried to steal my banking info. So no thanks. NEVER use that service.

[@Segarsomuthusamy]

Excellent videos about "outer space". It's interesting and educational.Thank you.

[@robertschlesinger1342]

Very interesting, informative, important and worthwhile video.

[@williamkopanchuk]

I don't really understand the numbers. If they don't know how many objects are why they give a percent of known objects?

[@navret1707]

My question exactly.

[@ccdimage]

It is a known unknown. A how many X in volume Y question where volume Y is very large. You can estimate it by taking a small part of volume Y call it y and measuring how much x there is. Then say the volume you measure y is 1% of volume Y and you count 100 x then you can estimate X is 10000.

We also know the gravitational mass by the effects on other objects. It's how we know how massive "Planet 9" is, even though we can't see it [yet]. (It could be a ring of objects, or a single planet, or a small black hole. All have the same gravitational mass).

its like the vaxx ine , they ''discover'' it at the speed of science 😂

[@amangogna68]

Great information !

[@steveswhirld]

did you all know uranus is blue in color ,,like a baboons,,,it also has a ring around it

Bravo Mr Hainaut et Merci …………… !!!!👍

[@chriskopec1858]

Thanks💗

[@jrtstrategicapital560]

Are these “near earth” objects classified as “co orbital” objects as well? Not a lot of folks realize that these co orbital objects are great for having satellites mounted on them to monitor the earth..

howt tf can you push away something that has that much energy stored into it. it makes no sense man.

[@ahsanullahkhan4495]

nice

[@Leo.Wirabuana]

should anyone not surprised if one day one of them collide with earth, we are not that small you know.

[@onebylandtwoifbysearunifby5475]

It has happened before. And with "starlink", we will lose the ability to see these forever.

We just use a super wide-angle telescope and look for objects that are moving - like that asshole Musk's starlink satellites.
