Neutron star gravity force on one kilogram
Neutron-star gravity force on one kilogram is the pull that a neutron star’s surface gravity would exert on a one-kilogram test object.
Also known as: one kilogram on a neutron star, neutron-star surface weight

A little perspective
Neutron star gravity force on one kilogram vs Aircraft carrier buoyant support force: weight comparison
The gravitational force on one kilogram at a neutron star’s surface is about 1,900 times the buoyant support force on an aircraft carrier.
FORCE
Neutron-star gravity force on one kilogram is the pull that a neutron star’s surface gravity would exert on a one-kilogram test object.
Aircraft carrier buoyant support force is the upward force from water that counteracts the weight of an aircraft carrier, enabling it to float.
Too small to see at this scale; the bar has not been widened.

Neutron star gravity force on one kilogram
Representative gravitational force: 1,900,000 MN; representative model; range 1,000,000 MN–3,000,000 MN.
About 1.9 TN on a 1 kg test mass in a Newtonian surface model for a 1.4-solar-mass neutron star with a 10 km radius. Relativistic gravity, rotation and the uncertain equation of state change the result.

The marked representative gravitational force is calibrated. Unmeasured illustration details are representative.
Aircraft carrier buoyant support force
Defined buoyant support force: 1,000 MN; derived calculation; range 800 MN–1,200 MN.
A defined 1.0 GN buoyant force balancing the weight of an approximately 102,000 tonne displaced mass at rest. Loading, seawater density and motion change displacement and support forces.

Why this measurement?
Why we use 1,900,000 MN
We compare the gravitational force on one kilogram at a neutron star’s surface. This is a representative comparison value; individual specimens or conditions can vary. The recorded range is 1,000,000 MN to 3,000,000 MN.
About 1.9 TN on a 1 kg test mass in a Newtonian surface model for a 1.4-solar-mass neutron star with a 10 km radius. Relativistic gravity, rotation and the uncertain equation of state change the result.
