Q: what do you know about boundaries of our solar system ?
| Option | Answer | Is Correct |

| 1 | The vast majority of our Solar System is still unknown. Its extent is determined by that of-’ the Sun’s gravitational field, which is currently estimated to concede to the gravitational forces of surrounding stars at roughly two light years (125,000 AU) distant. Some astronomers contend that the outer extent of the Oort cloud, by contrast, may not extend farther than 50,000 AU.Despite discoveries such as Sedna, the region between the Kuiper belt and the Oort cloud, an area tens of thousands of AU in radius, is still virtually unmapped. There are also ongoing studies of the region between Mercury and the Sun.Objects may yet be discovered in the Solar System’s uncharted regions. |
