what is the name of the star that appeared when jesus was born

Christians traditionally call it the Star of Bethlehem , and the Bible does not give it any other specific, proper name.

What the Bible Says

The Gospel of Matthew is the only biblical source that mentions this star.

It describes a star that appeared in the east, guided the wise men (Magi), and then “stopped” over the place where Jesus was.

Traditional Name

• The usual name used by Christians and in church tradition is “Star of Bethlehem.”

• Art, hymns, Christmas sermons, and modern articles all use this same title rather than a unique astronomical name.

Was It a Real Astronomical Object?

Different ideas have been suggested by scholars and astronomers:

• A special conjunction of planets (for example, Jupiter and Saturn appearing very close together).

• A comet or a nova/supernova that appeared unusually bright.

None of these theories is universally accepted, so the star’s exact physical nature remains an open question.

Religious Meaning

For Christians, the star mainly symbolizes:

• A sign of the birth of a king (Jesus).
• God guiding the nations (represented by the Magi) to Christ.

The emphasis in Christian teaching is more on this symbolic guidance than on the precise scientific identity of the star.

TL;DR:
The star that appeared when Jesus was born is commonly called the Star of Bethlehem , and the Bible does not give it any other formal name; what exactly it was astronomically is still debated.
