Outside the top four, the ranking of all the asteroids is uncertain, as there is a great deal of overlap among the estimates. The largest asteroids with an accurately measured mass, because they have been studied by the probe Dawn, are 1 Ceres with a mass of (939.3 ± 0.5) × 10 18 kg, and 4 Vesta at (259.076 ± 0.001) × 10 18 kg.
Four huge asteroids — and a fifth that's much smaller — are passing Earth on Thursday in their closest approaches to the planet ever recorded. 4 large asteroids, including 1 the size of a ...
The GBU-57A/B MOP (Massive Ordnance Penetrator) is a precision-guided, 30,000-pound (14,000 kg) "bunker buster" bomb used by the United States Air Force. [2] The GBU-57 (Guided Bomb Unit-57) is substantially larger than the deepest-penetrating bunker busters previously available, the 5,000-pound (2,300 kg) GBU-28 and GBU-37.

In the moments before NASA's DART spacecraft slammed into the asteroid Dimorphos in a landmark planetary defense test in 2022, it took high-resolution images of this small celestial object and its ...
The Tsar Bomba (Russian: Царь-бомба, romanized: Tsar'-bomba, IPA: [t͡sarʲ ˈbombə], lit. ' Tsar bomb '; code name: Ivan [5] or Vanya), also known by the alphanumerical designation "AN602", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested.
outer main-belt (a > 2.82 AU) A plot of inner solar system asteroids and planets as of 2006 May 9, in a manner that exposes the Kirkwood gaps. Similar to the position plot, planets (with trajectories) are orange, Jupiter being the outer most in this view. Various asteroid classes are colour coded: 'generic' main-belt asteroids are white.
