What type of orbit is the exoplanet in?
Circular
What is the transit method of finding extrasolar planets?
Transit photometry is currently the most effective and sensitive method for detecting extrasolar planets. It is a particularly advantageous method for space-based observatories that can stare continuously at stars for weeks or months.
What is transit as it relates to exoplanets?
A transit occurs when a planet passes between a star and its observer. When the exoplanet passes in front of the star, the light curve will show a dip in brightness. This data is part of why transits are so useful: Transits can help determine a variety of different exoplanet characteristics.
How do we discover exoplanets?
Bottom line: The most popular methods of discovering exoplanets are the transit method and the wobble method, also know as radial velocity. A few exoplanets have been discovered by direct imaging and microlensing.
How do we discover planets?

- Direct Imaging. Taking Pictures. 53 planets discovered.
- Gravitational Microlensing. Light in a Gravity Lens. 108 planets discovered.
- Astrometry. Minuscule Movements. 1 planet discovered.
What do we mean by a hot Jupiter?
Hot Jupiters are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (P < 10 days). The close proximity to their stars and high surface-atmosphere temperatures resulted in the moniker “hot Jupiters”.
Can gas giants be hot?
Gas giants are not all gas. The cores of the gas giants are crushed under tremendously high pressures and they are very hot (up to 20,000 K), while the cores of the ice giants Uranus and Neptune are at 5000K and 5,400K respectively. Gas giants have been found around more than a thousand stars by the Kepler mission.
How hot is a hot Jupiter?
The planet, discovered in 2017, orbits KELT-9 670 light-years away from Earth and has a surface temperature of 7,800 degrees Fahrenheit. The planet is so hot on its dayside, it actually tears hydrogen molecules apart.
How hot is Jupiter at night?
With an average temperature of minus 234 degrees Fahrenheit (minus 145 degrees Celsius), Jupiter is frigid even in its warmest weather.
