The Tsar Bomba was a three-stage bomb with a Trutnev-Babaev [28] second- and third-stage design, [29] with a yield of 50 Mt. [4] This is equivalent to about 1,570 times the combined energy of the bombs that destroyed Hiroshima and Nagasaki, [30] 10 times the combined energy of all the conventional explosives used in World War II, [31] one ...
NASA is working on a modelling study that considers the asteroid 101955 Bennu, which has a diameter of 246 meters and capable of a 1.15 gigaton impact, as a modelling target for the HAMMER concept. [ 4 ] [ 5 ] It is circling the Sun at 63,000 mph and 54 million miles from the Earth .
A B83 casing. The B83 is a variable-yield thermonuclear gravity bomb developed by the United States in the late 1970s that entered service in 1983. With a maximum yield of 1.2 megatonnes of TNT (5.0 PJ), it has been the most powerful nuclear weapon in the United States nuclear arsenal since October 25, 2011 after retirement of the B53. [1]
Many hypothetical doomsday devices are based on salted hydrogen bombs creating large amounts of nuclear fallout.. A doomsday device is a hypothetical construction — usually a weapon or weapons system — which could destroy all life on a planet, particularly Earth, or destroy the planet itself, bringing "doomsday", a term used for the end of planet Earth.
The Quadrantid meteor shower is one of the strongest, and quickest, meteor showers of the year. ... This particular asteroid is 2003 EH1, which takes 5.52 years to complete one orbit around the ...

First asteroid discovered from space; source of Geminids meteor shower. 3753 Cruithne: 5: October 10, 1986: Unusual Earth-associated orbit 4179 Toutatis: 4.5×2.4×1.9: January 4, 1989: Closely approached Earth on September 29, 2004 4769 Castalia: 1.8×0.8: August 9, 1989: First asteroid to be radar-imaged in sufficient detail for 3D modeling ...
Lucy was launched from Cape Canaveral SLC-41 on 16 October 2021, at 09:34 UTC [3] on the 401 variant of a United Launch Alliance Atlas V launch vehicle. It gained one gravity assist from Earth a year later on 16 October 2022, [12] and after making a flyby of the asteroid 152830 Dinkinesh in 2023, [13] it will gain another gravity assist from Earth in 2024.
