According to paragraph 1, how do scientists know that Callisto is made up largely of ice? A. A sample of its interior was taken by the Galileo spacecraft in the late 1990s. B. It has too low a density to contain much rocky metallic material. C. With a noontime surface temperature of...
Europa, one of Jupiter's moons, may also have subsurface water. As our need for water outweighs the Earth's supply, scientists wonder if we may one day mine for water on the other planets and moons in our solar system. Water has a lot of unique and amazing properties that make it ...
16K Planetesimals are bodies in space that are not large enough to be designated as planets but which combine with others to form bigger protoplanets. Learn more about the definition of planetesimals and protoplanets, how they are formed, and how they relate to other heavenly bodies. Related...
way is to go through the planet's core and gives them a submarine. As they travel, several sea monsters pursue them and they escape before surfacing on the other side. While this scene seems harmless, it defies what we know about planets. Planets do not have rocky surfaces and watery ...
Planets do not have rocky surfaces and watery cores. In our solar system, we have small rocky planets (Mercury, Venus, Earth, Mars) and gas giants (Jupiter, Saturn, Uranus, Neptune). The planets formed when material from the early solar disk (planetismals) collided and clumped together to...
How does the asteroid belt float? Why are there no planets in the asteroid belt? How was the asteroid belt discovered? Did the asteroid belt used to be a planet? How is an asteroid belt formed? Are there meteorites in the asteroid belt?
To help with matching the telescope type to the type of observing you plan to do, we have prepared a table that relates the design and aperture to the observing use (moon, planets, deep-sky, etc.). Generally, refractors are good for lunar and planetary observing, while reflectors are go...
