SUMMARY

A single planetary body in the universe exerts a gravitational field due to its mass. This gravitational field is fundamental to the formation and integrity of the planet itself. The existence of the planet is direct evidence of its gravitational influence, which acts on the individual particles that make up the planet. Without gravity, the planet would disintegrate and cease to be classified as a planet.

PREREQUISITES
  • Understanding of basic gravitational principles
  • Familiarity with planetary formation concepts
  • Knowledge of the properties of mass and gravity
  • Basic physics terminology related to forces
NEXT STEPS
  • Research Newton's Law of Universal Gravitation
  • Explore the concept of gravitational fields in astrophysics
  • Study the formation of celestial bodies in the universe
  • Investigate the effects of gravity on particle dynamics
USEFUL FOR

Students of physics, astrophysicists, and anyone interested in the fundamental forces governing planetary bodies.

Greetings everyone,

I am a first time poster. I suppose that my initial post will be slightly non-scientific.

This question would seem to to be related to the question asking "Does some event happen if no one is there to observe the happening?"

If the contents of the universe consisted of only one single planetary body, would that body exert a gravitational field?

Welcome to Physics Forums.

Yes. The fact that the planet exists is evidence that it has a gravitational field. Gravity is what causes planets to form and it is what holds them together. It would not make any sense for a planet to form and then it's gravity disappear. If that happened it would probably break apart and would no longer be considered a planet.
 
Ah, I did not take into account that gravity acts on the individual particles that constitute the planet.
