The nine eight planets in our solar system are commonly divided into two groups: Inner Planets - Mercury, Venus, Earth, and Mars. The inner planets are small and are composed primarily of silicate rock and iron. Outer Planets - Jupiter, Saturn, Uranus, Neptune and Pluto. The outer planets...
根据文章第三段"According to NASA,taking direct images of exoplanets presents a challenge because stars are much brighter than their surrounding planets-HIP65426 b is more than 10,000 times duller than its host star in the near-infrared(近红外光),and a few thousand times duller in the mid-...

But still, the Kepler-160 system appears strikingly similar to our own. "KOI-456.01 is relatively large compared to many other planets that are considered potentially habitable," Heller said. "But it's the combination of this less-than-double the size of the Earth planet and its solar type...
For example, if you use an Image control to display an image of the solar system, you can set the AlternateText property to The Solar System, and then set the DescriptionUrl property to an HTML page that further describes the image of planets orbiting the sun in the solar system. The ...
planets, roughly 10, 10 and 7 times the mass of Jupiter, orbit the star. The size of the planets decreases with distance from the parent star, much like the giant planets do in our system. And there may be more planets out there, but scientists say they just haven’t seen them yet....
