Andromeda is visible in which seasons in the northern hemisphere?

• A. Autumn and Winter
• B. Spring and Summer
• C. Winter only
• D. Autumn only

Answer: (A)

Seasonal visibility in the northern hemisphere hinges on Earth's orbit and where an object sits in the sky. Andromeda is located in a part of the sky that becomes opposite the Sun during autumn, so it rises after sunset and climbs higher as the night progresses, making it fairly easy to spot through winter skies. By winter it’s well placed for evening viewing. As spring approaches, the Sun moves into that same region, leaving Andromeda hidden in daylight and twilight. So Andromeda is visible in autumn and winter in the northern hemisphere, especially with a good dark sky and a pair of binoculars.
