Date Conflict needs resolution[edit]

"Piazzi observed Ceres twenty-four times, the final sighting occurring on 11 February 1801, when illness interrupted his work. He announced his discovery on 24 January 1801 ..."

Difficult to imagine how he could announce his discovery before his first sighting.

Can someone please clear this up? DDilworth (talk) 07:44, 14 October 2023 (UTC)[reply]

We CANNOT measure the mass of any of these objects[edit]

Since we cannot put any of these objects on a scale in a known acceleration we CANNOT know the mass of any of them. All we can know is the acceleration which they impart to other objects in the Solar System, But the acceleration is as we all learned in high school determined by the product of the Gravitational Constant and their mass. However the value of the Gravitational Constant has only been measured to four decimals, whereas because of three thousand years of astronomical observations combined with tracking of space probes we know the value of GM for most of these objects to at least eight decimals.

For example the value of GM for the Earth is 3.986 004 42 x 10^14 m^3/s^2, nine digits. To make the "mass" of a solar system body meaningful to non-scientists it can be convenient to divide the value of GM for the body by the value of GM for the Earth, and you end up with a meaningful and useful value accurate to at least 8 digits. But the moment that you ask for a value in pounds or kilograms you get a completely useless number which is only accurate to 4 digits. In particular if some amateur decides to create a personal numerical simulation of the motion of Solar System bodies by directly applying Newton's Law F=GM1M1/r^2, the result will be inaccurate because of the use of the inaccurate value of G.

The column for "Mass" in all similar tables throughout Wikipedia should therefore be replaced by a column containing the product GM. Jamescobban (talk) 22:59, 19 April 2024 (UTC)[reply]
