The Sun
Demonstration characteristics. The diameter of 109 diameters of the Earth, the gravity at the surface, at the equator 28 earth. The core temperature is 1.5 million degrees, the second is the space velocity of 617 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.
The platform of the lunar ship «Apollo 18». The photo was taken by an automatic station from the near-moon orbit. With modern optics and excellent conditions for shooting (airless space, a distance of 50 km) traces of astronauts stay on the Moon could be taken with a resolution of tenths of a millimeter. Traces of a lunar car are visible. The maximum distance from the spacecraft during such walks is an impressive 10 kilometers. And, again, in any archives of the Network we do not find detailed, sufficiently long filming of such remarkable voyages. The film captures two or three minutes of movement of the all-terrain vehicle in a circle. One of the weighty hooks of the supporters of the «lunar conspiracy» is the too rapid fall of the soil that escaped from the wheels of the car. Gravity and, accordingly, the acceleration of gravity on the Moon is six times less than the Earths.
