When does the constellation Orion disappear completely from the night sky in the northeast US?
Orion will be visible in the night sky at different times of the year. As the Earth progresses around the Sun, the stars (including those that make up Orion) will be above the horizon at different times of the day. If one cannot see Orion in the night sky, it's because it's above the horizon during the day, not at night. Wait six months and Orion will be visible in the night sky.
