Which of the following (as defined by the International Astronomical Union) is a celestial body orbiting a star or stellar remnant that is massive enough to be
rounded by its own gravity, not massive enough to cause thermonuclear fusion,
and has cleared its neighboring region of planetesimals?

a. comets
b. stars
c. dwarf planets
d. planets
e. asteroids

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

option number c is the right answer.
