Question 1

Neptune has winds in its atmosphere around ____.&#10;A) 800 km/hr&#10;B) 1000 km/hr&#10;C) 1300 km/hr&#10;D) 2200 km/hr

Accepted Answer

2200 km/hr&#10;

Question 2

This planet is tilted on its side on its orbital plane:&#10;A) Jupiter&#10;B) Saturn&#10;C) Uranus&#10;D) Neptune

Accepted Answer

Uranus is unique among the planets in our solar system because it rotates on its side with respect to its orbit around the Sun. This unusual tilt of about 98 degrees means that Uranus essentially rolls around the Sun on its side.

Question 3

Accepted Answer

Voyager 2 is the only spacecraft that has flown by Uranus, which it did in 1986, providing detailed images and data about the planet and its moons.

Question 4

Orbital irregularities, or perturbations, in the orbit of Uranus led to the prediction of the existence of&#10;A) Pluto&#10;B) Halley's Comet&#10;C) Neptune&#10;D) Ceres

Accepted Answer

Orbital irregularities in the orbit of Uranus led astronomers to predict the existence of another planet, Neptune, which was influencing Uranus's orbit through gravitational forces.

Question 5

To distinguish Uranus from Jupiter we call it a(an) ________.

Accepted Answer

The answer of To distinguish Uranus from Jupiter we call...

Question 6

______ was discovered by mathematical calculations.

Accepted Answer

The answer of ______ was discovered by mathematical calculations....

Question 7

Uranus and Neptune are known as ice giants.

Accepted Answer

Uranus and Neptune are classified as ice giants due to their unique interior compositions, which are significantly different from the gas giants Jupiter and Saturn, featuring more ices such as water, ammonia, and methane.

Question 8

Adam's calculations helped discover Uranus.
