It is recognized that the celestial bodies are accelerating their speed in moving apart. How fast are they moving apart now? Joe L. Ogan

OganSoul surfer provides a good explanation based on your question. Your question, however, is not consistent with your follow up. Your premise of acceleration doesn't hold for celestial objects smaller than galaxy clusters. If you put a hundred mice on a rubber sheet and let them run around...some would be closer to eachother even as you stretched the sheet. You could measure the expansion of the sheet but not provide a generalized figure for the expansion between any two mice.Planets are stable in orbit around the Sun. Their orbital speed/ acceleration is due to orbital mechanics. I don't think any acceleration or slowing of the orbital speed of Mercury, for example, has anything of signifigance to do with the position of Venus (or vica versa).
