There's a lot of excitement surrounding the "Transit of Venus," even though this rare astronomical event will yield little scientific value.
On Tuesday, Venus will cross the face of the sun. The transit will take about seven hours and begin at 6:09 p.m. EDT.
The next time Venus journeys across the sun will be in the year 2117, says Jack Lissauer, Kepler Mission co-investigator and planetary scientist at NASA Ames Research.
"This is the last chance for almost everybody unless we have huge medical advances," Lissauer says.
