Launched in 1977 to study the Solar system's gas giant planets, Voyager 1 is still operating. But now it's so far away that the Solar wind has weakened and a deluge of cosmic particles from intergalactic space is assailing it. Now interstellar space awaits. But where does the Solar system end and this new frontier begin?
The Oort cloud lies from approx. 5,000 to 100,000 astronomical units from the sun. It is suggested that the outer reaches of this system are affected more by distant stars than by our own star, the sun. So in effect, the end of our solar system lies somewhere within the outer reaches of this vast area referred to as the Oort cloud. Ethos_, Wed, 27th Nov 2013
The little film was excellent. I think the boundary between our star and the outside galactic stars is the position in space where the incoming energy is exactly balanced by the outgoing energy from our star.
will voyager have collected mass due to its own gravity as it passes through dust?
Yes, but the accumulation of mass via collection of dust particles will be so slight as to be insignificant.
BTW, I see that you are rather new to the forum barney so I would like to welcome you to these hallowed halls of wisdom.
Voyager will need a very long time indeed to acquire enough mass to be assigned that title. In fact, the universe will probably die the forecasted heat death before that remote eventuality occurs.
thanks Ethos. ive been on before but not for quite a while.
If it orbits the sun the it is part of the solar system. Radrook, Tue, 30th Dec 2014
