    Cosmological Data Error
Click For Summary
SUMMARY

The discussion focuses on the percentage error in cosmological data, specifically regarding the diameter and mass of the sun. The diameter is noted as 1.3914x108 meters, while the mass is 1.989x1030 kilograms. The orbital period of the sun is given as 2.75x107 years with a margin of error of ±9.1%. It is emphasized that the uncertainty in the sun's mass is primarily influenced by the uncertainty of the gravitational constant, which is correlated with the mass uncertainties of other astronomical objects.

PREREQUISITES
  • Understanding of cosmological measurements and their uncertainties
  • Familiarity with gravitational constant and its implications
  • Knowledge of astronomical object classification
  • Experience with data management and database creation
NEXT STEPS
  • Research the methods for calculating percentage error in astronomical data
  • Explore the implications of the gravitational constant on mass measurements
  • Investigate the definitions and challenges of measuring celestial object dimensions
  • Learn about database management systems suitable for astronomical data
USEFUL FOR

Astronomers, astrophysicists, data scientists, and anyone involved in the collection and analysis of cosmological data will benefit from this discussion.

I am currently creating a database of all the known cosmological objects, and need to know the percentage error in the following data:

Diameter of the sun: 1.3914x108 metres

Mass of sun: 1.989x1030 kilograms

I have the orbital period of the sun to be: 2.75x107± 9.1% years

So you are at star number 1 of more than a billion?

Check the publications for uncertainties. For the sun, the definition of "radius" itself is challenging, as it does not have a solid surface.
The relative uncertainty on the mass of sun is dominated by the uncertainty on the gravitational constant, and highly correlated with the uncertainty on the mass of all other astronomical objects.
