Question

The most unusual characteristic of Uranus is _____.

its green color
the icy cold temperature
the axis tilted at 98°
the methane atmosphere

Answer 1

the axis is tilted at 98 degrees

Step-by-step explanation:

Uranus is blue, not green; it has an atmosphere of hydrogen and helium, not methane. While it does have an icy cold temperature, that's not a very unusual characteristic for an outer planet. However, the tilt of the axis is unusual; no other planet is tilted almost completely on its side!
