Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the object classification?Irregular moons of Jupiter
2. What is the orbital inclination?High inclination, often exceeding 140 degrees
3. What are the Ananke group moons?They are small, irregular moons that travel around Jupiter on very wiggly, tilted paths. They are different from the big, round moons like Io and Europa.
4. Why do the Ananke group moons orbit in the opposite direction of Jupiter?Because they were captured from elsewhere, their paths go against Jupiter’s spin, so they move backward compared to the planet’s rotation.

Irregular Satellites: Moons with distant, eccentric, and inclined orbits, often retrograde, suggesting capture.
Gravitational Capture: The process by which a celestial body is trapped into orbit by the gravity of a larger body.
Protoplanetary Disk: A rotating disk of dense gas and dust surrounding a newly formed star, from which planets form.
Spectroscopy: The study of how matter interacts with electromagnetic radiation to reveal composition and properties.
