These days we have seen in the sky the first remarkable astronomical event in the newly released 2016 Catalina comet. This comet will be seen very faintly with the naked eye from Earth, but the only time we have the opportunity to admire him. And with binoculars simple spectacle worth it.
Why be the only time that will be felt Catalina comet was discovered in its approach to the Sun in 2013; and its discoverer was the asteroid tracking program “Catalina Sky Survey” hence the name.
It comes from the Oort Cloud, a spherical structure of comets rotating around the star of our solar system. It is very likely that as a result of a collision with a preceding object in the outer solar system or even with another member object of the cloud itself, suffered a violent enough impact to move from its orbit and guide you into our solar system.
The different gravitational forces of the sun itself and the other planets, caused this object approaches to our star in a hyperbolic orbit (non-cyclical orbit, therefore it will enter in our solar system, turn once past the Sun, it will rise again and driven away from our system). Therefore, Catalina, reconverted to wandering, will only be visible once our eyes.
The objects that make up the Oort Cloud are balls of dust and snow, of a size ranging between 10 and 50 km in diameter. And they are very interesting from the point of astronomical and biological standpoint, since we can consider traces the origin of the solar system. They would be like fossils of the same. Hence the high value to be studied and analyzed in its composition and watching the primal elements of the nearest part of the universe to us.
To observe Catalina simply need binoculars and direct our observation to the star Arcturus, one of the brightest of our winter sky. The locate from the end star shopping medium Osa both Mayor.En find Catherine. We appreciate its double tail, one in the direction of the solar wind because of our sun king and sublimation of water vapor, and the other ion tail left behind as a trace of its path in the sky.
