ASKAP J1839−0756 is an unconfirmed neutron star/magnetar candidate located in the constellation Scutum, approximately 13,040 light years from Earth. With a rotation period of 6.45 hours, as of 2025 it is the slowest rotating neutron star candidate ever discovered.[1] Objects with such properties are thought to be neutron stars with unusually very slow polar precession.[2]
