15 2 points Two stars are in a visual binary star system that we see face on. One star is very massive whereas the other is much less massive. Assuming circular orbits, which best describes their relative orbits in terms of orbit size, period, and orbital velocity? O The two stars would be at an equal distance from the center of mass, like an evenly balanced seesaw. They would orbit around the center of mass on opposite sides of a circular orbit-basically, a circle with the two objects always equally spaced apart. The orbital periods would be the same for each object. The velocity for the smaller-mass star would be faster than that of the more massive star since it has less mass and needs to move faster to keep up. The two stars would be at an equal distance from the center of mass, like an evenly balanced seesaw. They would orbit around the center of mass on opposite sides of a circular orbit-basically, a circle with the two objects always equally spaced apart. The orbital periods would be the same for each object. They would be moving with the same velocity. The larger-mass star would move in a smaller circle around the center of mass since it would be located closer to the center of mass, whereas the low- mass star would be found to have a large orbit farther from the center of mass. Both orbits would be concentric, located around the center of mass. The orbital periods would be the same for each object, similar to the objects on the seesaw. The velocity for the smaller-mass star would be faster than that of the more massive star since it has a larger orbit size compared to the massive star. O The larger-mass star would move in a smaller circle around the center of mass since it would be located closer to the center of mass, whereas the low- mass star would be found to have a large orbit farther from the center of mass. Both stars orbit around the larger star. The orbital period for the lower mass star is longer since its orbit is longer. The velocity for the smaller-mass star would be faster than that of the more massive star since it has a larger orbit size compared to the massive star. The lower-mass star would move in a smaller circle around the center of mass since it would be located closer to the center of mass, whereas the high- mass star would be found to have a large orbit farther from the center of mass. Both orbits would be concentric, located around the center of mass. The orbital periods would be the same for each object, similar to the objects on the seesaw. The velocity for the larger-mass star would be faster than that of the more massive star since it has a larger orbit size compared to the low-mass star
