Planets and stars. The History ofВ almost Everything

We love the Cosmos. We need the most important technical details – they are here. We need feelings and scope for imagination – this is taken into account in every possible way…

TheВ Sun

Demonstration characteristics. The diameter ofВ 109В diameters ofВ the Earth, the gravity at the surface, at the equator 28В earth. The core temperature is 1.5В million degrees, the second is the space velocity ofВ 617В km. from.

Interesting studies of the Sun are conducted by the European apparatus SOlar and Heliospheric Observatory (SOHO), since 1995. In particular, it was this station that discovered exotic objects with the size of a slightly more terrestrial Moon above the North Pole of the Sun. The American STEREO project is also interesting – a bunch of two remote devices forming a stereoscopic image of «our» star.

It’s really hot here…

Emission ofВ matter from the solar corona

Mercury

The diameter ofВ 4, 9В thousand kilometers, (about 0.4В terrestrial), the period ofВ revolution around its axis 58В earth days. Variations ofВ temperatures on the surface ofВ the planet range from minus 190В C at night toВ plus 430В degrees during the day. Acceleration ofВ free fall 3.7В m. sq., 2.5В times less than on Earth. The second space velocity is 4.25В km. from.

The equatorial rotation speed is just over 3В m. Thus, here is aВ note toВ the science fiction writers, from the onset ofВ aВ sizzling day, an astronaut can leave at aВ rapid pace. Further pictures ofВ the planet without comment, for aВ long psychedelic contemplation.

Venus

Acceleration ofВ free fall at the equator (gravity) is 0.9В terrestrial. The period ofВ revolution around its own axis is 225В terrestrial days. The radius is 6052В km. The atmosphere consists almost entirely ofВ carbon dioxide, clouds ofВ sulfuric acid vapor are floating inВ the atmosphere. Atmospheric pressure is 92В terrestrial. InВ practice, aВ gas whose density is equal toВ 7% ofВ the density ofВ water is already some kind ofВ liquid.

The temperature on the lower surface of such a gaseous ocean is 460 degrees Celsius. The atmosphere of Venus is involved in continuous circular motion. A complete revolution around the planet of a mass of carbon dioxide, at an altitude of 10—50 km. having a speed of about 100 ms. (at the surface – 1 ms) are performed in four days.

In the distant past, perhaps, Venus was quite suitable for inhabiting the known protein forms of life, the heavenly body. The maximum temperature on the surface reached barely 80 degrees Celsius, the atmosphere is rather sparse and transparent. However, a planetary catastrophe – a collision with a large asteroid or comet, perhaps the loss of a huge satellite – become a single planet, Mercury (there is such a version), all this changes. The morning star in one far from perfect moment changes the direction of movement around its axis, enveloped in a dense, corrosive atmosphere. Life, if it has ever been there, ceases.

Everything can be and not so bad. The photographic cameras ofВ the Soviet probe В«VenusВ», which produce images for one and aВ half hours (while the station was still В«livingВ») showed an interesting anomaly. Stones ofВ aВ characteristic elongated shape, aВ few minutes after the loud landing ofВ the apparatus, revealed themselves, as if bold oysters ofВ the earth.

Whether this is so, or the appearance ofВ cracks inВ the ston
