What weighs more a 100 pound Great Dane on Pluto or a 25 pound terrier on mars?

Weight depends on the gravitational pull of the celestial body. On Pluto, a 100-pound Great Dane would weigh approximately 38 pounds due to Pluto's lower gravity. On Mars, a 25-pound terrier would weigh about 9.4 pounds. Therefore, the Great Dane on Pluto weighs more than the terrier on Mars.
