A comet is a heavenly body of small dimensions, which consist of ice with flecks of dust and stone fragments. When approaching the sun the ice begins to evaporate, because the comet remains a tail, sometimes stretching for millions of miles. The tail of a comet consists of dust and gas.
The comet’s orbit
Generally, the orbit of most of the comet is an ellipse. However, rarely there are also circular and hyperbolic trajectories that move ice bodies in outer space.

Our Solar system is one of the constituents of the Galaxy. Here the milky way extends for hundreds of thousands of light years. The Central element of the Solar system – the Sun. Around it revolve eight planets (the ninth planet Pluto was excluded from this list because he has the mass and gravitational forces are not allowed to be in the same row with the other planets). However, each planet is similar to the following. Among them are small and really huge, icy and fiery, which consists of gas and dense.
The largest planet in the Universe is TrES-4. It was discovered in 2006 and it is located in the constellation Hercules. The planet is called TrES-4 orbits the star, which is at a distance of about 1,400 light years from planet Earth.
The largest planet
The planet TrES-4 – ball, which consists mainly of hydrogen. Its size is 20 times the size of Earth. Researchers claim that the detected diameter of the planet by almost 2 times (actually 1.7) larger than the diameter of Jupiter (the largest planet of the Solar system). The temperature of TrES-4 of about 1260 degrees Celsius. Continue reading
