Where are the Robinsons going in lost in space?

They lost orientation-= hence the title. There were many cases of bad science- one character, evidentally the navigator once remarked- we"re a little closer to home now, we just passed Uranus and Antares. Well maybe Uranus= as it is in the solar system., Antares, is however a far-distant star. it"s a bit like two truckers commenting, we"re a little closer to home now, we just passed Jersey City and Chunging China- say en route to Albany! Asimov dismissed this as a howler! It is not quite clear where the Robinson party was headed- presumably- like Star Trek- to seek out new life and livable planets.
