Question

Imagine another solar system, with a star less massive than the Sun. Suppose a planet with the same mass as Earth orbits at a distance of 1 AU from the star. How would the planet's year (orbital period) compare to Earth's year?

Answer 1

Considering that the star is less massive than the sun, the smaller mass of the star would provide a less strong force of gravity at any distance, and consequently a lower orbital speed. Thus, the year of the planet would be longer than that of the Earth.
