数年前に見た巨大な小惑星の名前は何でしょうか?


1

数年前、私はベネズエラの家族と一緒にいました。日時はわかりませんが、おそらく2007年頃の午後だったでしょう。巨大な流星が東から西へ「ゆっくり」移動しているのを見たとき、私たちは話していました。見た目は満月の約1/4。私たちの見方から迷子になるのにかなりの時間がかかりました(1分以上だと思います)。火の玉が燃えて道を離れるのが見えました。

ニュースでこれについて聞いたことがなく、この同じイベントが他の誰かに見覚えがあるかどうか、または以前に同じような経験をしたことがあるかどうかを知りたいと思いました。

つまり、これは巨大で、クラッシュするのを待っていましたが、幸運だったようです。

「岩」が見えるので、衛星ではありませんでした。火の玉と痕跡を区別できない流星のようではありませんでした。

日付はわかりません。

Meteors don't move slowly.

Large fireballs do occur, rarely, but they move pretty fast, a few seconds at most. Meteors that are bright enough to be seen in daylight are even rarer. When a meteor is falling you can't see the "rock". Even a large meteoroid is only a few metres across, and they are 50-100km up in the atmosphere, and surrounded by glowing plasma. Take a look at some of the videos of fireballs. Very few are during the day (because even bright fireballs are not clearly visible) and the few which are visible during the day are very well know (the 1972 daylight fireball or Cheblynsk)

What you saw cannot be a meteor. Because meteors don't look like that.

Re-entering space debris or satellites move more slowly, and can have more of a "burning" appearance than a meteor, but there is no mention of a satellite re-entry in the database: http://www.satobs.org/reentry/Visually_Observed_Natural_Re-entries_latest_draft.pdf For example on Jan 2007 the rocket for Corot-r (a space telescope launched by Russia) re-entered over the USA and generated many reports. That would not have been visible from Venezuela (and was in the middle of the night).

If you had an exact date then it would be possible to search more deeply, without it, this will probably remain a mystery. (I pondered briefly about a rocket launch from the Guiana site, but they always launch to the East, over the sea (for safety and efficiency) so that can also be excluded.

+1 because although admittedly unusual sounding this is the right SE site to ask about this kind of thing and you're responsive to comments. In Aviation SE I have seen discussions of why under certain conditions planes climbing near an airport will sometimes appear to hover or move in an unnatural way, and I've seen it myself so I know the feeling. I don't know of any astronomical phenomenon that can make a visible and resolved (you can see the size) object move slowly across the sky. Weather balloon, plane, or other atmospheric object most likely.

Artificial satellites take a minute or two, but they are usually dim and only seen at night, at the brightness of unremarkable stars. The only exceptions to this that I know of are satellite flares which tend to last only seconds, or intentionally reflective satellites like the Humanity Star, Mayak (Маяк), or the Orbital Reflector.
