- Ina hypothetical planetary system planet A is located 20 million kilometers from its star, and planet B is 60 million kilometers from the same star. Using mathematical and computational thinking, which statement accurately describes their orbits? Planet A moves faster than planet B because it is closer to the star, resulting in a shorter orbital period. Planet B moves faster than planet A because it is farther from the star, experiencing a greater gravitational pull. Planet B has a more elliptical orbit compared to planet A, influenced by the star's gravitational variations at greater distances. Planet A has a more circular orbit compared to planet B, as its closer proximity to the star stabilizes its orbital path. Clear my selection
- Which statements accurately describe Earth's orbit around the sun? Select all correct responses D The gravitational attraction between Earth and the sun causes Earth to o rather than flying off into space, demonstrating a balance betw gravitational force and centripetal force. Earth orbits the sun slower than Jupiter, as Jupiter's greater distance from the sun results in a longer orbital period. Earth's orbit is slightly elliptical rather than perfectly circular. Earth orbits the sun faster than Mercury due to its closer proximit to the sun,resulting in a shorter orbital period.
- Which timescale is most accurate for our current model of the solar system? A model of the solar system that begins 10 million years ago A model of the solar system that begins 4.6 billion years ago A model of the solar system that begins 13.7 billion years ago A model of the solar system that begins 1 billion years ago Clear my selection
