Gravity and force

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

How big is it?

1,900,000 MN of force

Representative gravitational force · representative model
Typical recorded range: 1,000,000 MN to 3,000,000 MN.

Scale illustration of Neutron star gravity force on one kilogram, calibrated to its representative gravitational force measurement.
The marked representative gravitational force represents 1,900,000 MN.

A little perspective

About 1,900 times the defined buoyant support force of Aircraft carrier buoyant support force.

Aircraft carrier buoyant support force: Aircraft carrier buoyant support force is the upward force from water that counteracts the weight of an aircraft carrier, enabling it to float.

Neutron star gravity force on one kilogram

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.

NASA Imagine the Universe — Neutron stars

The marked representative gravitational force is calibrated. Unmeasured illustration details are representative.

Aircraft carrier buoyant support force

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.

Defined examples — our methodology

The marked defined buoyant support force is calibrated. Unmeasured illustration details are representative.

Why this measurement?

Why we use 1,900,000 MN

For comparison, this page uses representative gravitational force. This is labelled representative model: an explicit comparison model rather than a claim that every example has the same value. 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.
