"Yes, seasons can last arbitrarily long times," Geoff Marcy, a veteran planet hunter at the University of California, Berkeley, wrote in an email to SPACE.com.

Seasons are for the most part controlled by the way a planet leans toward or away from its sun. For example, the Earth's axis does not run straight through the planet. Instead, it has a slight tilt that points the Northern Hemisphere toward the sun during part of the planet's orbit (causing summer) and away for another part (causing winter).

Other planets experience similar — and more extreme — seasonal changes. [The Strangest Alien Planets (Gallery)]

"The planet Uranus in our solar system has its North Pole spin axis pointed toward the sun during some 42 years, andrapidly fill the gasoline tank for continued racing, the storage tank is inadvertently not vented prior to use. Consequently, the highly flammable, pressurized gasoline vapors are allowed to come into rapid contact with the hot motor vehicle, often causing an unwanted fire or explosion.
In addition, prior art delivery systems have failed to eliminate unwanted spillage. Consequently, gasoline is often spilled on the hot motor vehicle during the delivery process. This spillage is also very dangerous and has also resulted in unwanted fires.
Similarly, in transferring toxic or hazardous liquids, spillage continues to be a primary problem, as well as unsafe disposal of the container bearing the concentrated toxic liquid after it is used.
Although these problems and difficulties have existed in the industry for many years, no prior art system
