Not all planets are. Warmth depends entirely on the atmosphere and how close it is to the star. for example, Mercury's daytime and nighttime are about 600 degrees Celsius apart, being about 300 C and -300 C respectively, and Venus has so much carbon dioxide, that the surface is three times as hot as on mercury, which means venus's surface would feel like a mushy candy bar left in the sun. however, Earth, whithout an atmosphere, would have an average temp of -18 degrees AT THE EQUATOR. this is why greenhouse gasses are important, because that is why we have nice temperatures like an average of 54 degrees Fahrenheit planetwide. Past us, most of the rocky planets ( and dwarf planets) have little to no atmospheres, so they have temperatures very close to absoulte zero. outside our solar system, a very common sight is a 'hot Jupiter' meaning a Jovian planet of around Jupiter's mass that orbits it's sun in less than an Earth Day. being this close has many consequences, one of which being if they are low-density they have a very good chance of being blown apart by solar winds. one such planet has an average daytime temperature of about 2400 degrees C, about 1000 degrees less than it's own parent star.
They are dark and cold.
The first factor is distance from the sun. Most of the planets are too close or too far from the sun making them too hot or too cold. All the planets other than Earth have unbreathable atmospheres or, in the case of Mercury, no atmosphere. The four outer planets are gas planets with no solid surfaces.
They all have a solid rock surface composition and I'm 10 years old
it circlles the sunUranus orbits the sun different from other planets as its axis of orbit is on it's side. As other planets orbit the sun from north to south, Uranus' poles are where other planets equators are. See the related link for more information.Like all the planets, the orbit is an ellipse.
These planets are very cold gas giant planets.
Without the planets orbiting the sun all the planets would be cold and dark
They are dark and cold.
All except earth and venus.
because its cold
Because all planets behind the earth are cold and all in front are hot this is because we are at peak temperature
All the planets farther away from the Sun is colder than Earth.
because inner planets are hot and outer planets are cold
All four of the gas giant planets are very cold. The coldest being the furthest one from the sun, Neptune.
hot planets i think are mercury and venus... cold planets i think starts from mars outward..
Well i have 2.THERE ALL CALLED PLANETS THEY ARE ON THE OUTER PART OF THE SOLER SYSTEM
Cold and it's not a planet it's a satellite
Some planets are hoot, some are cold, and some have moderate temperatures.
