The matter of the astronaut causes the antimatter to anhilate each other, creating energy close to the energy produced by the equation E=mc2.
This question presupposes the existence of an antimatter reactor. As far as I know, no such reactor exists, or has even been designed. Antimatter reacts with matter to produce energy with virtually no matter remaining. Such a reaction is thousands of times more powerful as nuclear reactions we have used on this planet. But antimatter is difficult to make and nearly impossible to handle. As soon as it touches anything, it is gone. There is a lovely quote from a researcher who has made antimatter often. He said that if all the antimatter made at CERN were put together and reacted with matter, the resulting energy would power a light bulb for a few seconds. This even though it is the most powerful reaction we know of. There just is not enough of it to react usefully.
This means that during space flight the astronaut is feeling a force which is 5 times that of gravity, therefore the astronaut is being pulled five times as much as he is standing on the planet
There are three main methods a nuclear bomb can destroy life. These three methods have major differences that set them apart in terms of the speed and extent of their effects. 1. The explosion The most obvious way a nuclear bomb can kill is by the explosion it creates. This explosion and the related shockwave releases an incredible amount of energy, killing any life within range almost instantly, and destroying human infrastructure, potentially killing large populations rapidly. Although the initial explosion causes significant damage to a large area, the next two methods of killing cause even more widespread damage. 2. The radiation The next method of nuclear destruction is the radiation released by the nuclear bomb. This radiation can kill most living creatures in a matter of days, and the radiation affects a larger area than the initial explosion. The radiation can persist for years and still be deadly. In addition, strong pulses of electromagnetic radiation released by the nuclear explosion can disable many electrical circuits, causing widespread blackouts and bringing entire countries to a standstill. 3. Nuclear Winter Nuclear winter is caused by extreme atmospheric changes following a nuclear explosion. During a nuclear winter, dust and debris becomes so thick in the upper atmosphere that light from the sun cannot reach earth's surface. Without sunlight, plant life will slowly begin to die, causing a collapse in most food chains on the planet. The lack of sunlight would also plunge the planet into an ice age, which would kill off plants and animals who are unable to adapt to the sudden drop in temperature. This method kills the slowest, but has the potential to cause a mass extinction of most species on the planet. It is often an unintended side effect of nuclear weapons, because it affects the entire planet, including the country that launched the attack.
No, the moon is not considered a planet. It is a natural satellite that orbits around a planet, in this case, Earth.
The planet closest to the sun is Mercury.
The amount of planet matter equal to that of the astronaut would annihilate.
No, he traveled to the Moon, which is not classified as a planet. Though technically, the Earth and Moon could be classified as a double planet.
An antiplanet is a hypothetical planet composed of antimatter.
Venus was the first planet on which a space probe landed.
no
She never landed on a planet. She was on the space lab. Only one planet has been landed on by man and that is the moon.
The mariner spacecraft first landed on Mars 1971 I think.
Dennis Tito was the first astronaut to travel to the planet Venus.
The Mariner spacecraft landed on the planet Mars, and the Apollo spacecraft landed on the moon.
Actually they already have visited a planet like the moon!
Nobody has landed on Saturn yet. For that matter, nobody has landed on ANY planet other than Earth, only on the Moon. The first planet to land on is expected to be Mars.
Human have landed on the Moon, not a planet. It was NASA's Apollo missions which successfully landed humans on the Moon from 1969 to 1972. No human has landed on any other planet besides Earth's Moon.
