The planet, within our solar system, that has nearly the same diameter as Earth, is Venus.
Venus is most similar to Earth in terms of mass and diameter. Venus is almost the same size as Earth, with a diameter about 95% that of Earth, and its mass is about 81.5% of Earth's mass.
Venus is often considered Earth's "sister planet" because it is very similar in size, with a diameter about 95% that of Earth.
With a radius of 3396km, the planet Mars is about the same size as the inner and outer core of the earth (which is around 3490km radius in total).
Venus, it is slightly smaller, and much hotter
Venus is slightly smaller than Earth, and its mass is about 81.5% of Earth's. Mars is much smaller, just over half (53%) of Earth's diameter and a mass only 10.7% of Earth's.

I'll make the large assumption that we're on the same planet. The Equatorial diameter of Earth is 7926.4 miles

That's the planet Mars .
The size of a black dwarf is about the same as some planets. They are expected to range in size from a little less than Earth's diameter to twice Earth's diameter.
With a radius of 3396km, the planet Mars is about the same size as the inner and outer core of the earth (which is around 3490km radius in total).
Yes Mercury (smallest), Mars and Venus (nearly the same size asEarth).
No. Mars has about half the diameter of Earth.
Venus, it is slightly smaller, and much hotter
no planet
Venus, hands down. Venus is very nearly the same size as Earth. Jupiter is several times larger.
No, the gravity of this planet will not be greater than that of earth. If the new planet has a mass equal to that of earth, its total gravity will be the same. There is a little ambiguity regarding 4 times earth density and half the earth's diameter if the idea is to keep the mass of this proposed planet the same as the earth. But setting that aside and assuming that the mass of the new planet is the same as earth's, the gravimetric field will be the same. Gravity is proportional to mass, and identical mass yields identical gravity. Now to the good part! The surface gravity of the new planet will be considerably higher than the surface gravity of earth. Both planets have the same mass and the same gravity, but a person standing on the surface of the new planet will be experiencing a whole lot more force pulling on him. All the mass of the new planet is beneath this person, but he's a lot closer to the center of gravityand will weigh a whole lot more.
