Mercury as a planet is a lecture. Planetary science is a field within astronomy that focuses on spheroidal, substellar astronomical objects apparently in an orbit around a star. The lecture primarily focuses on the orbital science of Mercury and the effects on the spheroidal, substellar astronomical object of revolving around the Sun.

You are free to take this quiz based on Mercury as a planet at any time.

To improve your scores, read and study the lecture, the links contained within, listed under See also, External links, and in the {{radiation astronomy resources}} template. This should give you adequate background to get 100 %.

As a "learning by doing" resource, this quiz helps you to assess your knowledge and understanding of the information, and it is a quiz you may take over and over as a learning resource to improve your knowledge, understanding, test-taking skills, and your score.

Suggestion: have the lecture available in a separate window.

To master the information and use only your memory while taking the quiz, try rewriting the information using more familiar points of view, or be creative with association.

Enjoy learning by doing!

Hypotheses

[edit | edit source]
  1. Planets are only those substellar, spheroidal astronomical objects in revolution around one or more stars.
  2. Planetary science is actually the study of the effects on any substellar, spheroidal astronomical objects of being in revolution around one or more stars.
