What else can I help you with?
What are the four planets larger than the earth and what are the smaller planets then the earth?
Jupiter, Saturn, Uranus and Neptune are much larger than earth. Venus (slightly), Mars (by half) and Mercury are smaller than earth.
How many planets in the Earth?
The earth is a planet, it has no known planets within.
How much mass do Planets have?
It depends on the planet. Some planets, like Jupiter, are made from gas. While others, like Earth, are rocky planets.
What planets are there around the Earth?
There are no planets orbiting Earth.
How is Mars and earth alike?
Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth.
Why doesn't earth's daily temperature vary as much as other planets?
It's because Earth has an atmosphere.
Why is there life on earth but not on anty outher planets?
There is life on other planets. Imagine, there are 1000 planets in the Universe for every grain of sand on the earth. That's how many planets there are, so scientifically, the chance that there must be life on other planets as well is much greater than the chance that there is no life.
Why giant planets have surface gravities very similar to earth's even though they have a lot more mass than the earth?
Giant, or Jovian planets do not have any discernable surface as they are comprised mostly of gases and are more like a liquid inside then solid. Also, these planets are a lot larger then the inner terrestrial planets and have much more gravity. The closest thing that would resemble gravity like the earth would be the moons of the large planets. These are also much smaller then the earth and would be a fraction of the earth.
Which planets have densities similar to earth?
The four inner, terrestrial or rocky planets all have similar densities, much higher than the four outer gas giant planets (though the outer planets are much larger and more massive).
Why do scientists on Earth want to know so much about other planets?
We may possibly know how Earth was created.
Which planet is bigger uranuus or earth?
Uranus is a Jovian planet, which are much larger the terrestrial planets, like Earth.
Why does earth contain so much water versus other planets?
As yet we are not certain as to the origins of Earth's water.
