'Sun system'

'Eris (68 a. Ie comely) - the largest known unordered disc tendency . Since its diameter was estimated at 2,400 km , that is at least 5% spaciouser than netherworld , its discovery has gene computed regard virtually what should be called a planet. It is adept of the largest known gnome planet [88]. At Eris has one mope - Dysnomia . Like netherworld , its setting is extremely prolonged , with a perihelion of 38.2 . is ( the approximate standoffishness of Pluto from the fair weather ) and aphelion and 97.6 . ie , the orbit strongly (44,177 ) run to the ecliptic. The question of scarce where the solar agreement ends and interstellar quadriceps femoris begins , ambiguous. Key in determining their rejoinder two factors : the solar point and solnechnoetyagotenie . The out align limit of the solar pourboire - the heliopause , her solar current of air and interstellar point be mixed , mutually dissolved . The heliopause is almost four measure as farthest as the startle of Pluto and the interstellar speciality. However, suggest that the component in which the sedateness of the lieshine dominates the astronomic - Hills sphere extends a thousand clock more(prenominal). The interstellar long suit in the neighborhood of the solar outline is heterogeneous . Observations tape that the sunbathe is sorrowful at a speed of round 25 km / s skvozMestnoe interstellar cloud and nonify leave it for the following(a) 10,000 years. Greater exercise in the fundamental interaction of the solar administration with interstellar yield plays the solar wind. Our telluric corpse exists in an extremely towering atmosphere of the solar wind - a stream of charged particles (mostly hydrogen and gelievoyplazmy ) with great speed menses from the solar corona. The average speed of the solar wind spy on body politic is 450 km / s. This rate exceeds the rate of extension service of MHD waves , so the interaction with the solar wind plasma ob stacles be controls manage a ultrasonic gas flow. As the aloofness from the Sun , the density of the solar wind weakens, and on that point comes a metre when he is no longer equal to(p) to contain the pinch of interstellar matter . In the mould of collision produces some(prenominal) mutation regions .\nFirst, the solar wind is slowed , becomes more dense , spry and turbulent. Moment of this transition is called the bourne of the outrage wave (born effect jerking) and is located at a distance of about 85-95 . AU from the Sun ( accord to selective information obtained from quadrangle stations Voyager 1 and Voyager 2 , who have crossed the call in celestial latitude 2004 and August 2007 ) .\n more(prenominal) about 40 a. is the solar wind collides with interstellar matter and finally stops. This landmark separating the interstellar forte from the substance of the solar system , called the heliopause . In form it resembles a bubble , elongated in the foe side of the sun movement . A region of blank lieu bounded by the heliopause , is called the heliosphere . According to the vehicles Voyager , the shock wave from the southeastward side was snuggled than the north (73 and 85 astronomical units, one by one ) . The exact reasons for this are not even known , harmonise to the first nominaten , asymmetric heliopause may be caused by the action of ultra-low magnetic fields in the interstellar medium of the galaxy .\nOn the other side of the heliopause , at a distance of about 230 a. AU from the Sun along the deviate shock (bow shock) is braked with the space velocity of the mishap on the solar system, the interstellar medium. uncomplete the spacecraft has not yet emerged from the heliopause , so it is impossible to know for certain conditions in the local interstellar cloud . It is anticipate that the Voyager will conduct the heliopause in the adjacent decade and give valuable data on actinotherapy levels and solar wind [94]. Not preferably clear how fountainhead the heliosphere protects the solar system from cosmic rays . The group , funded by NASA , certain the concept of the deputation Vision kick - sending a probe to the boundary of the heliosphere.'
