megaton TNT (MT): Unit of measure for the energy of an explosion. The Hiroshima atomic bomb liberated an energy of 0.015 MT. Minimal Orbital Intersection Distance (MOID); The MOID is the minimal distance between the orbits of two objects.

The huge 15 megaton airburst explosion which occurred in remote Siberia, near the Podkamennaya Tunguska River, at about 7:30 a.m. on June 30, 1908.

Megaton An explosive force equal to one million metric tons of TNT. The energy released in the explosion of one megaton of TNT is equal to 4.2 x 1022 ergs. MeV One million electron volts. Neutron An electrically neutral elementary particle.

4 megatons—more than 650 times the strength of the weapons developed by Oppenheimer during World War II. Security hea ringsIn his role as a political advisor, Oppenheimer made numerous enemies. The FBI under J.

Let's use the energy unit of 1 megaton of TNT (=4.2× 1015 Joules) to describe the energy of the impact. This is the energy one million tons of dynamite would release if it was exploded and is the energy unit used for nuclear explosions.

The energy delivered to the atmosphere by this impact was roughly equivalent to that of a 10- megaton thermonuclear explosion and caused the destruction of forest over an area of about 2,000 square kilometres.

La isla explotó con la fuerza de 100 megatones (la bomba de Iroshima fue de aproximadamente 20 kilotones). La explosión se escuchó hasta Madagascar (2 200 millas de distancia).

An object half a mile across packs a one-million- megaton punch, enough to threaten the globe, but objects this large are rare. "Tunguska-class" objects, that is, those measuring about 195 feet (60m) across, strike Earth far more frequently.

15 Ã- 1010 megatons of TNT per second. This actually corresponds to a surprisingly low rate of energy production in the Sun's core-about 0.3 W/m3 (watts per cubic meter). This is less power than generated by a candle.

17, there was an explosion with the power of a 20 megaton nuclear bomb above the Tunguska River in Siberia. Trees in the forest around the river were flattened up to 30 km from the explosion, which was heard up to 1000 km away.
| |
To give you some idea of the power of E=mc2 if we consider your basic 10 megaton nuclear explosion (pictured), the energy given off (10 megatons) represents the energy found in 47 grams of matter (about one and a two thirds ounces).
| |
When looked at in terms of matter and energy, imagine that the amount of material it takes to create a 1 megaton nuclear explosion could fit into a coffee jar.

Another rich source of information (also covering nuclear weapons) is the book "Megawatts and Megatons: A Turning Point in the Nuclear Age?" by Richard L. Garwin and Georges Charpak, 431 pp, $30, Knopf, New York, 2001.
| |
In a matter of just a few minutes they heat material to many millions of degrees and release as much energy as a billion megatons of TNT.

Here are educated guesses about the consequences of impacts of various sizes: Impactor Diameter (meters)Yield ( megatons)Interval (years) Consequences < 50 < 10 < 1 ...
| |
The energy of the blast was estimated to be between 10 and 20 megatons of TNT, 1,000 times more powerful than the bomb dropped on Hiroshima, or equivalent to Castle Bravo, the most powerful nuclear bomb ever detonated by the US.
| |
The shock wave from that explosion, estimated to be equivalent to 15 megatons of TNT, flattened trees over an area almost 50 km across (about 2,000 square km [500,000 acres]). Witnesses reported that its brightness rivaled that of the Sun.
| |
This energy is equivalent to that which would be released from the explosion of 100 billion one- megaton hydrogen bombs per second. The nuclear "burning" of hydrogen in the core of the sun extends out to about 25 percent of the sun's radius.
