This year's tree is an 80-foot-tall Norway spruce from Vestal, New York, in the Binghamton area.
About 5 miles of multicolored LED lights adorn the tree, which is topped with a star designed by Daniel Libeskind in 2018.
The three-dimensional Swarovski star weighs 900 pounds and features 70 spikes covered in 3 million crystals.
The tree, which is about 80-85 years old, is viewable at the Rock between West 49th and 50th streets and Fifth and Sixth avenues.

The official lighting happened a few minutes before 10 p.m. on Wednesday.
If you couldn't see the tree lighting in person, the Rockefeller Center's Instagram account provided some snaps during the night.
The tree+ will be lit daily from 5 a.m. until midnight until Jan. 13.
On Christmas Day, the tree remains lit for 24 hours. On New Year's Eve, it is lit from 5 a.m. until 9 p.m.
The Rockefeller Center Christmas tree has been a part of the New York holiday experience for 90 years. Workers at the Rock pooled their money to buy a tree in December 1931.
Two years later, it became an annual tradition as the first tree-lighting ceremony was held in December 1933.
