If you're planning a trip to Neptune's moon Triton, you'll want to head to the southern hemisphere where it's now just past mid-summer. Yes, distant Triton actually does have seasons, astronomers at ESO's Very Large Telescope recently determined. "We have found real evidence that the Sun still makes its presence felt on Triton, even from so far away," said astronomer Emmanuel Lellouch in an ESO press release. "This icy moon actually has seasons just as we do on Earth, but they change far more slowly." According to the first ever infrared analysis of Triton's atmosphere, the seasons last about 40 Earth years. But while summer is in full swing in Triton's southern hemisphere, there's no need to pack your bikini. The average surface temperature is about minus 235 degrees Celsius.
Not exactly Tenerife, is it?
