NASA can predict the speeds of the two Voyager craft very accurately.
The main problem is defining where the "end" of the solar system is.
These are known as interstellar probes, a space probe that has left, or is expected to leave the solar system and enter interstellar space. There are currently five out there; Pioneer 10 (now inactive), Pioneer 11 (inactive), Voyager 1 (functional), Voyager 2 (functional) and New Horizons (functional - currently on its way to Pluto). There are, or have been various other interstellar probes in the pipeline, including; `TAU mission` (a probe designed to reach a thousand astronomical units in 50 years), the `Innovative Interstellar Explorer` and the `Realistic Interstellar Explorer & Interstellar Explorer`.
Voyager 1 and Voyager 2 have both left the heliosphere, but neither has left the solar system. The edge of the solar system is considered to be the outer boundary of the Oort Cloud, The exact width of the Oort Cloud is not known, but its estimated that it would take Voyager 2 about 300 years to reach the inner boundary of it. To reach the outer boundary of the Oort Cloud, truly leaving the solar system, would take Voyager 2 something like 30,000 years.
Voyager did not discover any new planets. By the time Voyager was launched we already knew of all the planets in our solar system that we know of today. There were also two Voyager probes, not one. The first planet that either probe studied was Jupiter, which we had known for millennia. Voyager 1 flew by Jupiter in March 1979 while Voyager 2 flew by in July of the same year.
Jupiter is Gaseous Planet so no Lander/Rover can land on Jupiter. Voyager is basically a Spacecraft and spacecraft is used as flyby around a planet or object. It had a flyby of Jupiter in 1979. It is now outside the heliopause - the "bubble" of plasma coming from the sun otherwise known as solar wind. It is now out in what we consider interstellar space and still transmitting.
They are known as the poineer and voyager
Voyager 1 is about 109 AU (10 billion miles) from the Sun and has passed the termination shock, [See Link] and is entering the heliosheath, with the current goal of reaching and studying the heliopause, which is the known boundary of our stellar system.
Christopher Nolan, born July 30, 1970 directed the film Interstellar. He is most known for his independent films. He was born in London, United Kingdom.
Its known as interstellar space, as in the space between stars.
Voyager 2 is known for 2 things Being the only spacecraft to ever visit Neptune and Uranus Visiting all the outer planets
Voyager 1 and Voyager 2 have both left the heliosphere, but neither has left the solar system. The edge of the solar system is considered to be the outer boundary of the Oort Cloud, The exact width of the Oort Cloud is not known, but its estimated that it would take Voyager 2 about 300 years to reach the inner boundary of it. To reach the outer boundary of the Oort Cloud, truly leaving the solar system, would take Voyager 2 something like 30,000 years.
No astronaut has ever been to the 'outer reaches' of the solar system. As far as is known to the public, no human has ever been farther from earth than the moon is, and that's less than 1 percent of the distance to the nearest planet.
Magma that reaches the Earth's surface is known as lava.
