Who are earths neighbors?
Mars and Venus and the moon.
How strong is mars gravity compared to earths?
The acceleration of gravity on the surface of Mars is 3.722 m/s2 .That's about 38 percent of its value on Earth.
What are two factors that affect mars seasons?
Orbital distance from the Sun. Axial tilt with respect to the Plane of the Ecliptic.
Scientists hypothesize that life may have existed once on what planets?
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.
What do scientists believe can be found on mars rhat is also found on Earth?
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.
Which planet is similar to Mars?
Mars is very similar to Earth. Mars' year and day are very similar to Earth compared to other planets.
Do mars and earth have a similar mass?
No. Mars has about one tenth of Earth's mass. Venus, howevr, does have a similar mass to Earth.
What planet is similar to Earth?
Mars
Is Mars a similar to another satellite etc in your solar system?

Mars
Is Mars gravitational pull on the atmosphere less than earth similar to earth or more than earth?
It is similar
What is a small dense rocky planet similar to earth?
Venus, mars.
What planet has almost the same tilt axis as the earth?
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.
How planet earth similar to mars?
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.
What is another planet that has an environment similar to earth?
mars
