What was the first spacecraft to leave your solar system?

Answer 1

= Answer = None The following spacecraft have passed the last known body, ie Pluto Pioneer 10 and 11 Voyager 1 and 2 New Horizons will leave the solar system after flying past Pluto in July 2015. The solar system does not really end with Pluto. Besides the planets, there is a thin haze of dust (some of it bunched into comets). Any of this dust that is nearer to the Sun than to any other star may be in the gravitational hold of the Sun and so counts as part of the solar system. Voyager 1 is now near the Sun's heliopause [See Link]. The heliopause is the theoretical boundary where the Sun's solar wind is no longer great enough to push back the stellar winds of the surrounding stars. = Answer = It is true that none of the 5 spacecraft have to date left the physical environment of the solar system, however all 5 of them have sufficient kinetic energy to escape the Sun's gravity. Their escape from the solar system is therefore guaranteed, nothing that man or nature can do, short of an asteroid impact, can stop them from leaving the solar system. By having acquired sufficient velocity to exceed solar escape velocity, they can be said to have left the solar system. Even New Horizons, which will not complete its Pluto reconnaissance mission until 2014, has already escaped from the solar system.

Answer 2

The interplanetary probe Pioneer 10 left Earth on March 2, 1972, it was indeed off on a pioneering mission. In fact, the spacecraft led the way to all exploration of deep space.

Pioneer 10 was the first probe to travel through the Asteroid Belt and the first craft to explore Jupiter. On June 13, 1983, it became the first space probe ever to travel further than the Sun's most distant planet.

The Asteroid Belt is a Sun-orbiting span of rocky debris floating in space between Mars and Jupiter. The most distant of the nine known major planets, at the far edge of the Solar System, are Neptune and Pluto.

Since passing the outer planets, despite dwindling power onboard, Pioneer 10 has been sending back information by radio as it heads into interstellar space.

The Pioneer 10 and 11 missions ended in March 1997, their transmissions where sent to NASA as contact was restablished in 1998 and then continued to be apart of the study of advanced concepts of communications within their DSN (Deep Space Network) department. This continued until the last weak transmission in January 2002.

Even though this spacecraft is the first to venture out of our solar system being at 7.6bn miles or 82 AU ((Astronomical Unit) 82 x the distance between the Earth and the Sun which is about 93 million miles).

Pioneer 10 is heading towards a red star named Aldeberan within the constellation of Taurus, this star is 68 lightyears away and will take 2 million years to complete it journey.

Answer 3

Currently, no spacecraft have yet left the solar system.

The boundaries of the solar system are undefined, but most astronomers believe it is at the point where the Suns gravitational influence has no effect. This is about 2 light years from the Sun.

Voyager 2 - the furthest a man made spacecraft has ventured is only 0.001443 light years from the Sun in 2010.

Answer 4

Not quite, although two are getting close to the edge. The tricky part is figuring out where the solar system ends, and interstellar space begins.

The Voyager 1 and Voyager 2 space probes are past the orbits of Neptune and Pluto, but are well inside the Kuiper Belt and Oort Cloud. But they are approaching the "heliopause", the maximum extent of the solar wind from the Sun.

Answer 5

Voyager 2. It flew by all four gas giant planets in the 70's and 80's(Jupiter, Saturn, Uranus and then Neptune). It is now on its way out of the solar system - it hasn't really left our solar system yet, but will do one day.

Answer 6

The first spacecraft to leave our solar system was Voyager 1. It was launched by NASA in 1977 and crossed into interstellar space in 2012, making it the first human-made object to reach such a milestone.
