What is the name of the illuminated ball dropped in Times Square on New Year's Eve?

The illuminated ball dropped in Times Square on New Year's Eve is called the Times Square Ball.

The first ball descended in 1907, beginning a tradition that has made the object one of the world's most recognizable New Year's symbols. The original ball was made of iron and wood and was illuminated with electric lights. Later versions used increasingly sophisticated materials and lighting systems.

The current ball is a geodesic sphere covered with Waterford crystal panels and LED lighting. Its design has changed over time, including major updates for milestone celebrations. The ball is lowered during the final minute of December 31, reaching the bottom at midnight in New York City.

It is sometimes casually called the New Year's ball or the Times Square New Year's Eve ball. Those descriptions are understandable, but Times Square Ball is the standard name used for the object itself. It should not be confused with the separate countdown clock and digital signage surrounding it.
