Distance of Jupiter at Opposition

[matt]

Anyone know how far away Jupiter will be from Earth (km) when it reaches Opposition on the 6th of June?

Matt,

At opposition, Jupiter will be 643.98 million km from Earth.

Closest approach is the following day (little difference).

This year's opposition sees Jupiter farther away than average, but future oppositions will be better eg. while the diameter of Jupiter this year is 45.8 arcseconds, in 2010 it is 49.8 arcseconds.

Thanks Greg.
