Mars and Venus and the moon.
The acceleration of gravity on the surface of Mars is 3.722 m/s2 .That's about 38 percent of its value on Earth.
Orbital distance from the Sun. Axial tilt with respect to the Plane of the Ecliptic.
Yes, demonstrably the planet Earth has life. Scientists are currently looking for life on Mars (no proof of life recognized there yet) and are speculation that some extrasolar planets may be in the Goldilocks zone for life.
Planetary scientists have a lot about Mars over the past 40 or so years of robotic exploration. The earliest probes discovered Mars is heavily cratered in the southern latitudes, as much as the Moon, but the northern latitudes are much less cratered, such that scientists began to suspect an ancient ocean was responsible for resurfacing the northern parts, erasing signs of past impacts. By counting the number of craters in a given region, we can determine the relative ages of each terrain. Combining images and topographic data, scientists can trace ancient shorelines (multiple sea levels, as the seas dried up or evaporated). Observations of the south pole revealed a frozen carbon dioxide ice cap with seasonal variations that contain a historical record of the Mars atmosphere. Mars has been and is thought to still be volcanically active. Volcanoes are present, of the kind that created Yellowstone or Hawaii on Earth; tectonism without plate tectonics. Traces of methane in the atmosphere are replenished annually, suggesting either replenishment by volcanoes or life forms. Geomorphological and structural observations show that water flowed across the Martian surface. We can have estimates of the size and composition of the core of Mars, and magnetic data showing local magnetism but no global magnetic field. Water ice has been found just below the surface in the northern hemisphere. We have some mineral maps, and radar images of the subsurface layering. In short, a lot of scientific data has been found, and piecing all that together to determine that past geological history of Mars is an ongoing endeavour.
Mars is very similar to Earth. Mars' year and day are very similar to Earth compared to other planets.
No. Mars has about one tenth of Earth's mass. Venus, howevr, does have a similar mass to Earth.

It is similar
Mars is the planet that has a tilt axis similar to Earth's, with Mars having a tilt of about 25 degrees compared to Earth's 23.5 degrees. This similarity in tilt axis is one reason why Mars experiences seasons similar to Earth.
Earth is similar to Mars because we know that life is possible on earth and some scientists believe that life is also possible in mars because it has some things which is also present in Earth and is needed for all living things.
Yes, they are similar in size, and there is evidence that there was once water, a stabil magnetic field, and an atmosphere on Mars.
