in groundbreaking discovery A team of scientists has identified the largest planet known to exist in the universe. This planet is named OGLE-2016-BLG-1195Lb It is about 13 times the size of Jupiter, the largest planet in our solar system, and orbits a star about 22,000 light-years from Earth. The discovery challenges our current understanding of planet formation. And it raises new questions about the diversity and distribution of planetary systems in the universe.
Here are the top 10 largest planets in the universe. Based on the mass and radius of the planet:
- OGLE-2016-BLG-1195Lb: 13.4 Jupiter mass, 1.11 Jupiter radius.
- Tres-4b: 8.3 Jupiter mass, 1.8 Jupiter radius.
- WASP-17b: 7.5 Jupiter mass, 1.99 Jupiter radius.
- WASP-12b: 6.2 Jupiter mass, 1.79 Jupiter radius.
- HAT-P-1b: 5.5 Jupiter mass, 1.38 Jupiter radius.
- HD 100546 b: 6.9 Jupiter mass, 1.9 Jupiter radius.
- HAT-P-2b: 8.6 Jupiter mass, 1.17 Jupiter radius.
- HD 17156 b: 3.2 Jupiter mass, 1.5 Jupiter radius.
- Kepler-17b: 4.4 Jupiter mass, 1.97 Jupiter radius.
- Kepler-10c: 17.2 Earth masses, 2.35 Earth radii.
Note that the Kepler-10c, although not as large OGLE-2016-BLG-1195Lb But it is the largest rocky planet ever discovered. The density is close to the world.
How did scientists find these planets? The most common method is called the transit method. This involves observing the star’s dimming as the planet passes in front of it. Measuring the magnitude and duration of these diminishing brightnesses. Scientists were able to deduce the size and orbit of the planet. Another method is called radial velocity method. which involves measuring small wobbles of stars caused by Earth’s gravity
Now back to the largest planet in the universe. OGLE-2016-BLG-1195Lb It was detected using a technique known as gravitational microlensing. It relies on the bending of light by a massive object to amplify the light of a distant star. This method is rare but effective. This is because it can detect planets that are far from their parent star and other techniques can miss them. In the case of OGLE-2016-BLG-1195Lb, The planet and its star are aligned in such a way that Earth’s gravity causes a brief distortion of the star’s light. but clearly noticeable
What do we know about OGLE-2016-BLG-1195Lb Unfortunately, there aren’t many. Due to the distance and limitations of the microlens method. We cannot directly observe the atmosphere, composition, or surface features of planets.
We only know that it orbits the star at a distance of approximately 2.3 Astronomical Units (AU), where 1 AU is the average distance between the Earth and the Sun. which is farther than the inhabitable zone This is the distance from the star where liquid water may exist on the planet’s surface. But that doesn’t mean the planet isn’t inhospitable. It’s likely OGLE-2016-BLG-1195Lb.
