Question

question #1
of the following, which is a pair of terms that have no direct relationship (or \correlation,\
in scientific terms) in astronomy?
period of revolution and average temperature.
mass and gravity axial tilt and seasons
density and color

Explanation:

• Period of revolution (orbit duration) relates to distance from the star, which affects average temperature (farther = colder).
• Mass directly influences gravity (Newton’s law of gravitation: $F=G\frac{m_1m_2}{r^2}$).
• Axial tilt causes seasons (unequal sunlight distribution).
• Density (mass/volume) and color (related to composition, temperature, or surface properties) have no inherent direct correlation in astronomy.

Answer:

density and color
