Near-Earth object

A near-Earth object is a Solar System object whose orbit brings it close to the Earth.

Their least distance from the Sun, their perihelion, is less than 1.3 AU. NEOs include near-Earth asteroids NEAs and near-Earth comets.

They include more than ten thousand near-Earth asteroids NEAs, near-Earth comets, some solar-orbiting spacecraft, and meteoroids large enough to be tracked in space before striking the Earth. Collisions in the past have had a significant role in shaping the geological and biological history of the planet.

In some cases NEOs hit the Earth. Most of these meteors explode harmlessly in the upper atmosphere. But some NEOs are dangerous. We try to find out when one is going to hit Earth using impact prediction. On 30 June 1908, a meteorite of around 45 metres in diameter exploded over the basin of the Podkamennaya Tunguska River. It released an energy of 10–15 megatons of TNT and destroyed roughly 2.000 square kilometres of forest. Such an explosion, similar to one of the biggest nuclear weapons, could have razed London about as far out as the M25 ring road. However, because the location was remote, no deaths were recorded. The Association of Space Explorers estimates that a Tunguksa-like event happens two or three times every thousand years on average. An asteroid roughly 10 km in diameter is thought to have hit Earth 66 million years ago and caused the K / T extinction event, including the extinction of all non-avian dinosaurs.

Pino - logical board game which is based on tactics and strategy. In general this is a remix of chess, checkers and corners. The game develops imagination, concentration, teaches how to solve tasks, plan their own actions and of course to think logically. It does not matter how much pieces you have, the main thing is how they are placement!
