As a result, craters would be more widespread on the Martian surface. This is because there is less atmosphere from less outgassing, it is likely that erosion would be less important as well resulting into craters being widespread on Martian surface.
If Mars were smaller, it would have undergone less volcanic and tectonic activity because its interior would have cooled more.
<span>But the relative size of these three Chinese population groups of 160 million will soon change. As a result of the country’s low fertility rates since the early 1990s, China has already begun experiencing what will become a sustained decline in new entrants into its labor force and in the number of young migrants. The era of uninterrupted supplies of young, cheap Chinese labor is over. The size of the country’s population aged 60 and above, on the other hand, will increase dramatically, growing by 100 million in just 15 years (from 200 million in 2015 to over 300 million by 2030). The number of families with only one child, which is also on a continued rise, only underscores the challenge of supporting the growing numbers of elderly Chinese.</span>
<span>The orbital period will be 5.196 earth years.
The period of an orbit is proportional to the square root of the cube of the semi-major axis. The semi-major axis of earth is 1 AU (actually 1.000001018 AU, but for this problem 1 is close enough). The hypothetical planet will have a semi-major axis of 3 AU. So making the ratios with earth's year being 1, earth's semi-major axis being 1, the planet's year being y, and the planet's semi-major axis being 3, we get the following ratio.
1 / 1^(3/2) = y / 3^(3/2)
Raise the denominators to the 3/2 powers.
1/1 = y/5.196
Multiply both sides by 5.196
5.196 = y
So the orbit period will be 5.196 earth years.</span>

only god knows
next time , ask a considerable question please.
