A castors images is a versatile rolling device that features a wheel in a mounting frame. They are commonly used for chairs, workbenches and heavy machinery that need to roll smoothly across floors. Stem casters, on the other hand, feature a cylindrical-shaped rod for mounting.

Castor Images

The star Castor – which appears as one of the two bright stars in the constellation Gemini the Twins – is actually part of a multiple system. Rather than two separate stars, the brightest component in the Castor system is double, and a spectroscope reveals that each of these stars reflects light from a companion star.

This six-star system – whose two largest components are hot A-type stars – isn’t visible in the night sky directly, but they are all visible using a small telescope. The other three, which are cooler M-type red dwarf stars, aren’t as well-defined and will be spotted only with a larger telescope.

Why They Are Called Castor and Pollux

The stars Castor and Pollux are often associated with yin and yang, the contrasts and complements of life. They are also referred to as the twins or Dioscuri in Greek mythology.

How to See them

If you want to try to spot Castor and Pollux, you can use the Big Dipper as a guide. Or, if you’re in the Northern Hemisphere, you can use the constellation Orion the Hunter as a guide to find them. You can even star-hop from Orion to Castor and Pollux by drawing an imaginary line from Orion’s bright star Rigel through its bright star Betelgeuse, extending about three times the distance between these stars.
