Question

Which gaseous giants did Renaissance scientists such as Galileo know about? Check all that apply.

Answer 1

Answer:

The gaseous giants that Renaissance scientists such as Galileo knew are:

- Jupiter.

- Saturn.

Explanation:

Firstly, we can eliminate the option of Mars because it's not a gaseous giant, this name applies to Jupiter, Neptune, Saturn, and Uranus.

By another side, the Renaissance happened between 1300-1600 a.C., and by this reason, any planet discovered after that date wasn´t known by the Renaissance scientist, such as Uranus (discovered in 1781) and Neptune (discovered in 1846), then, the options that apply are Jupiter and Saturn, in the case of Saturn, Galileo could see its rings himself.

Answer 2

Answer:

The correct answer is:

Jupiter and Saturn

Explanation:

Solar system has 8 planets. 4 are rocky and 4 planets are gaseous. Gaseous planets are Jupiter, Saturn, Neptune and Uranus.  

Renaissance scientists such as Galileo knew about Jupiter and Saturn, Uranus was discovered by William Herschel in late 1700s and Neptune later.

Jupiter and Saturn were discovered by Galileo in 1610 while observing night sky through telescope. He turned it on Jupiter and understood that it had 4 large moons orbiting it. This was an astonishing discovery because it clarified that Earth was not the center of the Universe as the geocentric view supposed.
