At present only one of these planets has been found to transit the face of its parent star. Its radius is that of a slightly inflated gas giant. Models of the structure and evolution of these planets are beginning to show how clues to their evolutionary history may be encoded in their ...
Student: Exoplanets are planets that orbit around a star other than our Sun, right? 学生:外行星是那些轨道绕着恒星而非绕着太阳的星球,对吧? They are not in our solar system. 它们不在我们的太阳系中。 Professor: Right. 教授:对。 They have different... what are called "host stars". 它们...
Giant planet or 'failed star?' Newfound mystery world blurs the lines Is Pluto a planet or not? Who cares! Our love for the King of the Kuiper Belt is stronger than ever 95 years later Large alien planets may be born in chaos, NASA's retired exoplanet-hunter finds ...
Whilst in our solar system, the rocky planets are closest to the Sun, and the gas giants are on the outside, it should not be taken as a rule. Many exoplanets are gas planets which orbit close to their stars. According to theGeminiObservatory, there are gas giants that cling to their ...
Our solar system is located in the Orion arm of the Milky Way galaxy. It has eight planets, each of which orbit the sun at the center of the solar system. Pluto was once thought of as the ninth planet. However, discoveries lead to a change in the definit
Are gas planets larger than rocky planets? Which terrestrial planet is the largest? What was the first planet to form in our solar system? What's the biggest planet in the known universe? Why is Jupiter the largest Jovian planet? Which planets in the Solar System...
Finally, a black hole could make itself known by interacting gravitationally with celestial objects like planets, stars, asteroids or comets, which brings us to a key question: How close does our hypothetical black hole pass by our solar system? Clearly, the closer it passes, the worse the da...
or larger than, Jupiter - which led to the term "Super-Jupiter" being coined. Far from suggesting that gas giants were more common than rocky (i.e. "Earth-like") planets, these findings were simply due to the fact that Jupiter-sized planets are simply easier to detect because of their...
Despite decades of study, scientists still don't know exactly what dark matter is made of. They do know it's not made of ordinary atoms — the same kind of matter that makes up stars, planets, and people. That kind of matter is called "baryonic," and dark matter appears to be "non...
The discovery, outside our Solar System, of giant planets similar to Jupiter but much closer to their star, posed a serious puzzle for astronomers, because giant planets of that kind cannot form in such zones. Planets form in a disc of gas and dust that surrounds the young star.在我们的...
