This video starts with the Moon , runs through our solar arrangement ’s rough and gasoline planets , and then takes us from our steady - sized Sun to the grownup hypergiant star , all to a pulse - thump measure . make for a crash - track in cosmic scale .
The video is n’t gross – it omits the Neptune - sized Uranus and the now demoted Pluto ( not to mention the lately discoveredbiggest star ever , but that ’s hardly the video ’s fault ) and there aresome minor technical errorsin the demonstration of the lead . And , it should be pointed out that , outside our own Sun and Betelgeuse , we have n’t direct observe the sizing of the stars in this video , and these sizes are just secure surmisal base on apparent brightness , temperature , and distance .

But the overall point of this telecasting – to show just how comparative size really is , and how unthinkably large heavenly objective really are – is jolly much spot - on . If nothing else , I never quite realized how modest Mars actually is compared to Earth , or just how tiny our Sun can really count compared to some of its truly massive cousins .
