Các câu ví dụ cho từ planets

1. NASA has announced the discovery of new planets in the past, but most of those worlds were either too hot or too cold to host water in liquid form, or were made of gas, like our Jupiter and Neptune, rather than of rock, like Earth or Mars.

NASA đã công bố việc phát hiện ra các hành tinh mới trong quá khứ, nhưng hầu hết các thế giới đó đều quá nóng hoặc quá lạnh để chứa nước ở dạng lỏng, hoặc được tạo thành từ khí, như sao Mộc và sao Hải Vương của chúng ta, chứ không phải bằng đá, như Trái đất. hoặc sao Hỏa.

2. TESS, roughly the size of a refrigerator with solar-panel wings, is equipped with four special cameras to survey 200,000 stars that are relatively near the sun and thus among the brightest in the sky, seeking out those with planets of their own.

3. Like Kepler, TESS will use a detection method called transit photometry, which looks for periodic, repetitive dips in the visible light from stars star caused by planets passing, or transiting, in front of them.

4. One reason is red dwarfs have a high propensity for Earth-sized, presumably rocky planets, making them potentially fertile ground for closer examination, said David Latham, TESS science director for the Harvard-Smithsonian Center for Astrophysics.

5. Also because red dwarfs are so small, and their planets orbit more closely than the Earth does to the sun, the dip in light from a planetary transit of a red dwarf is more pronounced compared with a larger star, Latham said.

6. “It’s easier to find interesting planets around smaller stars,” he said.

7. Latham said fewer than 10 rocky, Earth- or super-Earth-sized planets have previously been confirmed, and NASA hopes to double or triple that number through the TESS mission.
