小行星 2024 YR4 撞击月球概率上升至 1/25

2025-06-30 14:49 by 人猿泰山之智斗恐龙

小行星 2024 YR4 基本不可能撞击地球,但 2032 年 12 月撞击月球的概率提高到了 1/25。若撞击真的发生,预估将在月球表面形成一个约 1 公里直径的新撞击坑。虽然月球本身无需防御,撞击也不会对月球轨道运行有任何影响。但撞击所造成的抛射物有可能进入地球同步轨道范围,对部分卫星系统造成干扰风险。这也提醒我们,太空防御的范畴不应限于地球,整个地月系统的安全亦不可忽视。

How Does Bitcoin Mining Work?

Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
