Why does a planet have no seasons?

Answer 1

Whenever a planet has an axial tilt, it has seasons. All the planets have seasons with the exception of Mercury, which has no atmosphere and Venus where its thick atmosphere keeps an almost constant temperature.

Answer 2

Mars is most like Earth - but even that's not saying that it's "like" Earth. With 1/3 the gravity and a mostly carbon dioxide atmosphere, there's little chance you'd be able to enjoy its seasons. However, if your patient, NASA is tentatively planning a manned mission to visit it in the 2040s, with the prospect of perhaps initiating terraforming (make it more like Earth) in subsequent visits. "How are they going to do that?" The same way Earth is suffering from global warming - by producing greenhouse gases. They also plan on "growing" some air. "How???" The same way air is "grown" on Earth - plants. Plants "inhale" carbon dioxide, and "exhale" oxygen. They figure by about 2150 or so, it may be inhabitable to some degree. Now, if you'd like to leave the comfort of our solar system, there's about a dozen other planets that are similar to Earth. Only problem is, they're several light years away. Long drive? You betcha! Even the fastest space ship we have would take about a thousand years to get there. (A "light year" is the distance travelled in one year at light speed, which is just under 186,300 miles per second.) John "Skip" Bruscato

Answer 3

No, several of the planets have seasons. Not all planets have seasons like Earth, but do experience some. Seasonal variability depends on planets distance from Sun, inclination of orbit, tilt of planet and a few other details.

Answer 4

Without going into too many complications, the simple answer is:

Earth, Mars, Saturn, Uranus and Neptune.

They are the planets with large axis tilts. Of course, the effect of the Sun at the distance of Uranus and Neptune is fairly small at any time of the year.

Answer 5

A planet would have no seasons if it did not ever change the angle of its rotation relative to the sun. As the earth turns on its axis, it is 23 degrees tilted to one side, like a top about to fall over. The axios of rotation spins itself, every 365 days, which gives us our seasonal changes. The shortest days, in fall and winter, are the coldest. The longest days, in the summer, give us more energy from the sun on a daily basis, and are warmer. In the Southern Hemisphere, the seasons are the opposite of those in the northern, so January in Brazil would be their summertime.

Answer 6

no it doesn't because it only has a tilt of 3.13 degrees which is not enough for seasons.And it is a planet

Answer 7

Mars and( of course) the Earth are the planets that have seasons. And there has said to be frozen water found on Mars, too! Freaky!

Answer 8

Our Planet Earth only!!
