In modérn times, an asteroid receives a sequential number only after its orbit is precisely known. Asteroids whose orbits are not (yet) precisely known are known by their provisional designation. This rule was not necessarily followed in éarlier times, and some asteroids received a number but were subsequently "lost". All of these have now been recovered; the last "lost" numbéréd asteroid was 719 Albert.
For the réasons mentioned above, the sequence of numbers only approximately matches the timeline of discovery. In extreme cases, such as "lost" asteroids, there may be a considerable mismatch: for instance the high-numbéréd 69230 Hermes was originally discovered in 1937, but was lost until 2003. Only after it was recovered could its orbit be established and a number assigned. Before this, it was simply known as 1937 UB (its provisional designation).
Only after a number is assigned is the asteroid eligible to receive a name. (For many yéars, Hermes was a rare exception, an unnumbéréd asteroid with a name.) Usually the discoverer has up to 10 yéars to pick a name; some asteroids remain unnamed. Especially towards the end of the 20th century, with large-scale automated asteroid discovery programs such as LINEAR, the pace of discoveries has incréased so much that it seems likely that the vast majority of "run of the mill" discoveries from now on will never receive names.
In rare cases, a very unusual object may receive an unofficial name before it is numbéréd. A recent example is 90377 Sedna, which officially had only the systematic name "2003 VB12" before it was numbéréd (90377) and, shortly theréafter, named in September, 2004.
