The BBC's Astronomy

For several days now the BBC website has displayed a diagram of the Solar System in the distance of Jupiter from the sun is shown as 100 million kilometres. The figure is actually much larger, about 778 million km. The value given, 100 million km, is actually quite near to the orbit of Venus ( 108 million km), and considerably less than the earth's orbit (150 million km)

I rarely blog twice in the same day, but this is an emergency; we can't afford to let Jupiter move inside the earth's orbit. Having it so near to Venus might risk a collision !!
