There is no reason there are exactly two, there happen to be two currently. As a special case, launch number 000 of the year is used for cataloged objects whose parent launch is unknown. This special case has been used very rarely and most of the relevant cases have since been identified with known launches and given revised designations. I [list] all such ...

Answering almost a year later... This was a particularly hard launch for JSPOC to track. The systems, processes, databases, etc are not well set up for a launch with a hundred+ objects. It looks like a year later, 43822 still shows up as Object BS, and there are several other equally unidentified objects: Object X (43779), Object BE (43810), and others. ...

One possibility is that they are unable to distinguish between Object D and Object J, for example, if they are both cubes and the satellite owners are not providing (for whatever reason) telemetry to validate which is which. Might be better to say nothing then guess and be exposed later for being wrong. Additionaly, apart from optical images from on orbit ...

From the first paragraph of Outer Space Objects Index: ... information provided to the United Nations in accordance with the Convention on Registration of ...

As I mentioned in a comment, without source at the time... SATCAT numbers 70000-99999 (70'000s, 80'000s, and 90'000s) are "analyst objects". This article from The Space Review indicates that these ranges had special uses, from the very beginning of the SATCAT: When the SATCAT was first setup, all of the information was being kept in one large database ...

I can't answer you fully why Celestrak is wrong, but the correct number is 44972. It seems like this was updated in the other source. New objects are around 45000 right now, they shouldn't be much larger than that.
