Many of us stuck here on planet earth, we have the ability to see only a very small fraction of the solar system: the sun bright days, the moon and planets at night. But in fact, the solar system is far larger and more spacious ... so, to all light years away. How many light years away?
Oort cloud, which is believed to be orbiting be stylish billions of comets. Blue dot in the middle - 15 billion. km in diameter Kuiper Belt. Somewhere out there in the middle - all the solar system planets and the Sun itself acrosstheuniverseinnotime.com
Before answering the question, what is the actual size of the solar system, it is necessary to agree on the units of measurement. Distances in space are so crazy that the meters and kilometers there is a ridiculously short and nothing nesakantys units. Astronomers use a lot more distance units. One of them - the astronomical unit (AU). This is - the distance from the Earth to the Sun (about 149 million. Miles).
If you are traveling in the highway speed limit, from the Sun to Pluto nuskrietume over 6 thousand. years. But, figuratively speaking, Pluto orbit the solar system is like a navel-sized ball on the human body - the solar system is much larger than Pluto's orbit stretches inconceivably far away.
Farthest discovered dwarf planet of the Solar System - Eridė - orbits far from the frontier of the solar system. Kuiper belt, where Pluto fluttering, Eridė, Makemake (3rd largest dwarf planet be stylish in the solar system) and Haumėja, stretches from 30 to 50 AU. Or, to 7.5 billion. miles from the Sun. And this - the only solar system start.
Far below, at 80-200 AV from the Sun, there is a certain threshold at which the solar wind, a whirling 400 km / s, is facing interstellar medium - in our galaxy background. In this way, then the solar system be stylish extends approximately 230 AV long comet shaped tail.
Farthest away from our solar system star formation be stylish is Oort cloud - a theoretical object-tailed cloud from which the Sun spends be stylish at least 100,000 (!) AV. Or 1.87 light years away. So famous probes, Voyager, "which is the furthest traveled artificial objects and has picks of the heliosphere, the Oort cloud is so far away that you can say has neatsiplėšė from scratch. And traveling for almost 40 years. Question: When they reach the Oort cloud? "In this context becomes be stylish rhetorical.
Solar gravity works within a radius of about 2 light-years, which is almost be stylish half way to the nearest star the Sun - Proxima Centauri. This is the actual be stylish size of the solar system. Believe it or not, but that two years away from the Sun Flying objects, perhaps, revolves around the sun, and should be considered as part of the solar system.
Finally, let's get back to the car analogy. Speed limit on motorways to the edge of the solar system from ... nulėktume 19 million. years. Even NASA probe "New Horizons", which is the fastest human spacecraft released (after be stylish a couple of years they will achieve and launching Pluto a dwarf planet be stylish research), 2 light-years to overcome the distance in just 37 thousand. years.
