Stars relative size
WebbFigure 19.6 shows how such measurements work. Seen from opposite sides of Earth’s orbit, a nearby star shifts position when compared to a pattern of more distant stars. Astronomers actually define parallax to be one-half the angle that a star shifts when seen from opposite sides of Earth’s orbit (the angle labeled P in Figure 19.6).The reason for … WebbIn Physics the student will be able to: Know that static equilibrium occurs when forces are balanced. Sketch streamlines around an aerofoil and explain lift. Reproduce Archimedes' principle, and explain buoyancy. Know the relative size of the gravitational force on the Earth's surface and on the moon's surface.

WebbIn a double star, or binary, system ( see binary star ), each star attracts the other gravitationally and orbits about a unique point, the centre of mass of the pair. If the plane of their orbits lies edge-on toward Earth, each star will be seen to eclipse the other once each orbital period. Such a system is known as an eclipsing binary.
WebbThe Andromeda stars simply pass by. But galaxies are more than just stars. They contain giant clouds of gas and dust. And, when galaxies collide, these clouds smash into one another. The clouds contain the raw materials needed to make new stars. It is the collision between clouds that has triggered a starry baby boom! WebbOur Galaxy, the Milky Way, is a huge spiral of stars about 100,000 light years across. About 100 BILLION star populate the Galaxy. The sun and its nearest stellar neighbors are quite similar in size and temperature, and so the "orange" remains a good size reference. However, the distance is another matter altogether.
