Our own Sun is 1.4 million km across (870,000 miles). That’s such a huge number that it’s hard to get a sense of scale. The Sun accounts for 99.9% of all the matter in our Solar System. In fact, you could fit one million planet Earths inside the Sun!
Astronomers use the terms “solar radius” and “solar mass” to compare large and smaller stars, so we’ll do the same. A solar radius is 690,000 km (432,000 miles) and 1 solar mass is 2 x 1030 kilograms (4.3 x 1030 pounds). That’s 2,000,000,000,000,000,000,000,000,000,000 kg.
One star in our galaxy is Eta Carinae, located approximately 7,500 light years away, and weighing in at 100 solar masses.
That means that Eta Carinae weighs, 100 multiplied by 2,000,000,000,000,000,000,000,000,000,000 kg!!!
It’s also 4 million times as bright as the Sun!
How is it that the star, Eta Carinae, which weighs so much! be sustained and kept in motion like that in outer space? … For that matter: how do the trillions of stars - found in billions of galaxies – which can weigh so much - sustain and carry all that weight like that?
How is it that our own planet Earth can move at speeds of 1675 km/h, 465 meters/second, 1040 miles/hour; that for every second - you’re moving almost half a kilometer through space, and you don’t even feel it !
How can the Earth and the moon and Sun just hang in space with nothing visible holding it up??? … it’s like it’s just there suspended in space … there’s no strings or ropes or anything like that holding it up? (Job 26:7)
How does our God sustain it all?
