Researchers at the Instituto de Astrofisica de Canarias in the Canary Islands has discovered a super-Earth that orbits red dwarf star GJ 740 in just 2.4 days. For comparison, Earth takes 365 days to revolve around the sun, this exoplanet does so in less than a week, or two days, nine hours, and thirty minutes to be exact. The TESS satellite will continue to observe this super-Earth and could provide more information on the planet in the future. Read more for a video and additional information.
The data also indicated the presence of a second planet with an orbital period of around 9 years, and a mass similar to that of Saturn. However, its radial velocity signal could be due to the magnetic cycle of the star (like the Sun), so more data is required to confirm that the signal is really from a celestial body.
- Computerized star locating telescope: The Celestron NexStar 127SLT is a computerized telescope that offers a database of more than 40,000 stars, galaxies, nebulae, and more. The telescope locates your object with pinpoint accuracy and tracks it.
- Compact and portable: This telescope for adults and kids to be used together is ideal for weekend camping trips or excursions to dark sky sites. Its compact form factor makes it easy to transport and assemble just about anywhere.
- Maksutov-cassegrain optical design: The NexStar 127SLT is the second-largest in the SLT family. The 127mm aperture gathers enough light to see our Solar System and beyond. View Saturn’s rings, Jupiter’s cloud bands, and the Moon in brilliant detail.
- Fast setup with skyalign: Celestron’s proprietary SkyAlign procedure has you ready to observe in minutes. Simply center any 3 bright objects in the eyepiece and the NexStar SLT aligns to the night sky, ready to locate thousands of objects.
- Bonus free starry night software: The NexStar 127SLT Computerized Telescope includes a free download of one of the top consumer rated astronomy software programs for an interactive sky simulation.
This is the planet with the second shortest orbital period around this type of star. The mass and the period suggest a rocky planet, with a radius of around 1.4 Earth radii, which could be confirmed in future observations with the TESS satellite,” said Borja Toledo Padron, the first author of the report titled ‘A Super-Earth on a Close-in Orbit Around the M1V Star GJ 740.’
