In addition, comets can carry the names of the people who discovered them, e.g., comet Halley, comet Machholz, comet shoemaker–levy 9 comet or Mac Note.
Movement and spatial distribution
All comets are members of the Solar system. They, like the planets, are subject to the laws of gravity, but move very peculiar. All the planets revolve around the Sun in one direction (which is referred to as “direct” as opposed to “reverse”) on nearly circular orbits that lie roughly in one plane (the Ecliptic), while comets move in both forward and reverse directions on highly elongated (eccentric) orbits, inclined at different angles to the Ecliptic. It is the nature of motion immediately gives the comet.
Long-period comets (orbital period greater than 200 years) come from regions located thousands of times further than the most remote planets, and their orbits are tilted at all angles. Short-period comets (period less than 200 years) come from the region of the outer planets, moving in the forward direction for orbits lying close to the Ecliptic. Continue reading
The U.S. space Agency plans to launch a probe, equipped with a solar sail. He will leave earth orbit and go to the distant asteroid due to the pressure of sunlight. Like the ships of the discoverers of the 15th century, in 2018, a small space probe will unfurl the sail and start a journey to a faraway asteroid, marking the beginning of a new phase in space exploration.
The idea of using solar sails for space flight was proposed almost a hundred years ago, Soviet rocketry pioneer Friedrich Zander. It was based on the fact that Photons of light can exert pressure on the illuminated surface, giving him his momentum. Therefore, if you expand behind the ship a giant mirror, his speed will gradually increase without using fuel.
However, the first experimental devices were established only at the very end of the twentieth century. This is because space sailboats should be very easy, and their embodiment in life became possible only after the emergence of a truly compact electronics. Continue reading
The planets and moons in orbit of the Sun
The largest planet in the Solar system. this is a Jupiter belonging to the class of gas giants. Ancient astronomers were able to detect and assign a very unusual name this planet. Named in honor of one of the most revered Roman gods, Jupiter is not in vain was honored to be the namesake of the thunder gods. For large-scale weather events, continuously produced in the atmosphere of the giant, strength and scale can outdo the deeds of the most powerful gods! Imagine the worst stormy weather on our planet. And now imagine the same thing, but only 10 times more intense and more powerful. These horrific lightning strikes, as if the gods went crazy and wants to destroy everything. Wild, wild the storm that engulfs everything in its path, and sometimes of centuries.
Jupiter is not alone in its orbit, having 67 different dimensions of the satellites. Like any ordinary giant planet has attracted much attention of scientists. A lot of research spacecraft was sent to Jupiter during the long years of study. Periodically, during the great opposition, Jupiter looks like the brightest star in the heavens. In this period of time activates the monitoring planeteurodisco ground-based and orbiting telescopes. Continue reading
