which planet is the prettiest?
how long is a day on neptune?
what is the composition of jupiters atmosphere?
do planets prefer being closer to or farther from the sun?

Explanation:

A testable hypothesis requires a question that can be objectively measured. "Which planet is the prettiest?" and "Do planets prefer being closer to or farther from the Sun?" are subjective (beauty and preference for non - living planets are not objectively measurable). "How long is a day on Neptune?", "What is the composition of Jupiter’s atmosphere?", and "Which planet has the most moons?" can be measured through observation and data collection.

Answer:

• How long is a day on Neptune?
• What is the composition of Jupiter’s atmosphere?
• Which planet has the most moons?
