Some factors that make a planet habitable include being located in the habitable zone, a stable star, the right mass, the ability to hold an atmosphere, and the presence of liquid water. Life has been on its way to dominating planet Earth for the past 3.7 billion years. What started as ...
alone in the universe? To begin to understand what makes a planet habitable, and thus where to look for life both within and outside of Earth's solar system, scientists need to understand what in planetary formation and what in its subsequent evolution combine to produce a habitable planet.do...
This work reviews factors which are important for the evolution of habitable Earth-like planets such as the effects of the host star dependent radiation an
This blue gem has harbored life for over 3.5 billion years and, barring unforeseen catastrophes, promises to continue for billions more. But, what makes life on earth possible? Explore the 10 key elements that make our planet a haven for life....
What main factors determine the health of a terrestrial ecosystem? What factors determine the distribution of organisms over Earth's surface? Explain how the biosphere interacts with the atmosphere. Why is the Earth's outer core so hot?
He explained that his team considers a Kepler planet as potentially habitable if it meets two criteria: (1) its radius is less than 2.5 Earth radii (1.5 Earth radii being conservative), and (2) the planet's orbit is within the optimistic HZ, calculated based on the particular star’s pro...
A. It should be as big as the Earth. B. It should be a gas planet. C. Must be around a planet like the sun. D. It must have liquid water. 相关知识点: 试题来源: 解析 B 宜居行星必须具备固体表面,而气态行星没有固体表面,因此不适合生命存在。选项B描述了宜居行星不应该具备的特征,所以...
A moon orbits a planet, not the Sun. The moons of Mars, Deimos and Phobos, are believed to have been asteroids. They strayed too close to Mars, whose gravity pulled them into an orbital path. The Earth's Moon is believed to have been created in the early solar system by a planet ca...
