I'm not sure what you mean by "Earth-like", or even "twelve times smaller" (one twelfth the mass? one twelfth the radius?), so I can't really answer this question.
Whichever version of "twelve times smaller" you mean, it would be unlikely for such a planet to retain a significant atmosphere or liquid water, so they wouldn't be very "Earth-like" by any definition that makes sense to me. The 1/12 mass variant would be slightly larger than Mercury and a bit smaller than Mars, and the 1/12 radius variant would be about the size of Ceres.
What else can I help you with?
Are the first four inner planets larger or smaller than earth?
From the Sun:Mercury is innermost and smallest (about the size of our Moon.)Venus is next and almost exactly the size of the Earth, just a shade smaller.Earth is next and it is - well- the Earth!Mars is the last of the rocky - Earthlike planets and it is smaller than Earth.See a picture comparing the sizes at: http://en.wikipedia.org/wiki/File:5_Terrestrial_planets_size_comparison.png
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.
What percent of the planets are smaller than the earth not including Pluto?
3 of the 8 planets (Mercury, Venus, Mars) are smaller than Earth.
What percent of planets are smaller than earth?
37.5% not including PlutoFirst Answer:50% including Pluto.Second Answer:Of the eight planets in our solar system, three are smaller than earth. 3/8 = 38%.However, we also know (to date) of more than a thousand other planets, orbiting distant stars. None of these planets so far is smaller than earth, but that it because planets as tiny as ours are difficult to detect. We expect probably half of all planets would be our size or smaller.
What percent of the planets are bigger than Earth?
There are 8 planets Mercury (smaller than Earth) Venus (smaller than Earth) Earth Mars (smaller than Earth) Jupiter (bigger than Earth) Saturn (bigger than Earth) Uranus (bigger than Earth) Neptune (bigger than Earth) so 3 smaller & 4 bigger than Earth 37.5% smaller than Earth 50% bigger than Earth
How big is Earth from the other planets?
Earth is one of the smaller ones.
Which plants are smaller than earth?
There are many planets smaller than Earth, including Mercury, Mars, and Venus. While these planets vary in size, they are all smaller than Earth in terms of diameter and mass.
How many earth planets fit into the moon?
The Moon is a lot smaller then the Earth.
Why are extrasolar planets more massive than earth?
Most of the known extrasolar planets are more massive than Earth because massive planets are easier to detect. We have detected planets smaller than Earth.
What percent of the planets are smalller than earth?
There are 8 planets Mercury (smaller than Earth) Venus (smaller than Earth) Earth Mars (smaller than Earth) Jupiter (bigger than Earth) Saturn (bigger than Earth) Uranus (bigger than Earth) Neptune (bigger than Earth) so 3 smaller & 4 bigger than Earth 37.5% smaller than Earth 50% bigger than Earth
Is Haumea bigger or smaller than earth?
Like all dwarf planets, Haumea is significantly smaller than Earth.
Is earth larger or smaller than all the other planets?
Of the seven other planets that orbit the sun, three are smaller than Earth and four are larger.
