1. What is the shape of most planets' orbits around the sun?
A). highly elliptical
B). circular
C). spiral
D). slighlty elliptical
The shape of most planets' orbits around the sun is A) highly elliptical.
To arrive at this answer, you can use your knowledge of planetary motion or utilize a reliable source such as reputable astronomy textbooks, scientific articles, or educational websites. The generally accepted model for planetary orbits is Kepler's laws of planetary motion, which states that planets orbit the sun in elliptical paths. This means the shape of their orbits is closer to an elongated circle than a perfect circle.
