Pluto is a Dwarf Planet not just a planet. — Preceding unsigned comment added by 68.146.172.219 ( talk) 22:29, 23 April 2013 (UTC) reply

There's a "dubious" tag that claims "Geom. albedo can be >1, as shown here for Enceladus|date=August 2012". This has been re-wording to make it clearer, and the tag removed. Eteq ( talk) 15:38, 14 May 2013 (UTC) reply

The formula is practically useless since it doesn't give the function ${\displaystyle I(\alpha )}$. How is someone supposed to find the phase integral? Sir Cumference π 19:37, 3 March 2017 (UTC) reply

This formula serves not for giving ${\displaystyle I(\alpha )}$. ${\displaystyle I(\alpha )}$ is derived from observations. Stas ( talk) 17:46, 4 March 2017 (UTC) reply

How is anyone supposed to derive such a formula empirically? Sir Cumference π 01:18, 6 March 2017 (UTC) reply

From measuring brightness of the object on different phase angles. Look Phase curve (astronomy). Stas ( talk) 12:38, 8 March 2017 (UTC) reply
