百武二号彗星(C/1996 B2)是一颗非周期性彗星,由日本鹿儿岛业余天文学家百武裕司于1996年1月30日在日本鹿儿岛县发现,是他发现的第二颗彗星。该彗星于1996年3月25日最接近地球(距离地球约135万公里),该彗星由2月初的10等猛增至3月底的0等。蓝绿色彗头配以3月底时彗尾长达120度,细长的蓝色彗尾横跨北斗七星至半个天空,令不少亲眼目睹的天文爱好者着迷,同年5月1日通过近日点。

3月25日,哈伯望远镜拍摄到百武彗星彗核物质分裂的样子,同时地面天文爱好者亦拍摄到此现象。3月26日至28日,美国和德国的天文学家使用伦琴X射线天文卫星(ROSAT)发现彗星的X射线辐射,这是人类首次探测到彗星发射X射线,且其强度也是天文学家始料不及的。百武彗星的X射线是在彗星内部形成还是太阳风与彗星物质的猛烈撞击还没有定案。

Comet Hyakutake (Japanese pronunciation: [çʲakɯ̥take], formally designated C/1996 B2) is a comet, discovered on 31 January 1996, that passed very close to Earth in March of that year. It was dubbed The Great Comet of 1996; its passage near the Earth was one of the closest cometary approaches of the previous 200 years. Hyakutake appeared very bright in the night sky and was widely seen around the world. The comet temporarily upstaged the much anticipated Comet Hale–Bopp, which was approaching the inner Solar System at the time.
