P2_5 The Apparent Magnitude of α Orionis Supernova
... The star α Orionis (Betelgeuse) is to become a type II supernova at the end of its life. Some have postulated that this supernova will be bright enough that it will be visible during the day. Betelgeuse will have an apparent magnitude of around -8.7, brighter than Venus, which can be seen when the s ...

Is there life in space? Activity 2: Moving Stars and Their Planets
... Q. Most of the planets that have been discovered orbit their stars at a tilt closer to 0 degrees than to 90 degrees. Why? A. The signal is more evident when the tilt is lower. The telescopes are not perfect, so they can only detect star motions that are very large. The largest motions occur when the ...

What causes the moon to change in appearance

As the moon orbits –the curved path of a celestial object or spacecraft around a star or planet—Earth, it appears as though the moon is changing its shape in the sky. This is because as the moon changes its position, the amount of sun ...

Orrery
An orrery is a mechanical model of the solar system that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; but since accurate scaling is often not practical due to the actual large ratio differences, a subdued approximation may be used instead. Though the Greeks had working planetaria, the first orrery that was a planetarium of the modern era was produced in 1704, and one was presented to Charles Boyle, 4th Earl of Orrery — whence came the name. They are typically driven by a clockwork mechanism with a globe representing the Sun at the centre, and with a planet at the end of each of the arms.
