Which method could detect a planet in an orbit that is face-on to the Earth?
The most common method to detect planets in face-on orbits to Earth is the transit method. This technique involves measuring the decrease in brightness of a star as the planet passes in front of it, causing a transit. By observing periodic dimming of the star's light, astronomers can infer the presence and characteristics of the orbiting planet.
Do other planets orbiting stars have seasons or eclipses?
Its most likely that they do. Any planet with an axial tilt will have seasons throughout its orbit. Eclipses of orbiting moons are also likely to occur on these exoplanets, though it would be rare to find an orbiting moon that is almost the same apparent size as the star - as with Earth.
What planet in one astronomical unit front the sun?
That would be Earth.
What is transit of Venus?
The passage of the planet Venus as it crosses in front of the sun, in opposition to the earth.
What methods has led to the most discoveries of massive planets orbiting near their parent stars?
The radial velocity method and the transit method have been most successful in discovering massive planets orbiting near their parent stars. The radial velocity method detects planets by measuring the wobble of the star caused by the gravitational pull of the planet, while the transit method detects planets by observing the dip in brightness as the planet passes in front of its star.
Which planet is in front of Saturn?
The planet which is immediately closer to the Earth than Saturn is Jupiter. The sequence of planets, starting with the one closest to the sun, is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.
Which planet can transit the sun?
The planet Mercury is the only planet in our solar system that can transit across the face of the sun as seen from Earth. This event is known as a transit of Mercury and occurs when Mercury passes directly between Earth and the sun.
Which of the following might be evidence for an extrasolar planet?
Potential evidence for an extrasolar planet includes observing a star's wobble due to the gravitational pull of an orbiting planet, detecting a dip in a star's brightness as a planet passes in front of it (transit method), or directly imaging a planet near a star using advanced telescopic techniques.
What is the passage of a planet in front of a star called?
The passage of a planet in front of a star is called a planetary transit. This event causes a small dip in the star's brightness that can be observed from Earth. Transits are important for studying exoplanets and determining their properties, such as size and orbit.
Is there evidence that there are other planets orbiting other stars?
Yes, there is. There is evidence of over 300 "exo-planets", planets that are orbiting other stars. Because the pull of gravity goes both ways, it can be said that a sun orbits the planet in addition to the planet orbiting the sun. Because suns are much more massive than planets, the motion of the planet in its orbit is far greater than the motion of the star, but the stars DO "wiggle" a bit. This "wiggle" is sometimes detectable, especially if the planet is itself quite massive - like a "super-Jupiter". And sometimes, the planet passing in front of the star blocks a teeny bit of the starlight, causing the star to appear to be slightly less bright.
What planet is Venus next to?
Mercury is in front of Venus (to the sun) and Earth is right behind.Mercury is formaly next to Venus!! :)
How do you know that stars have planets orbiting them?
There are two tools that astronomers use to determine that a far-off star has planets. 1. Occultation: When a planet passes in between the Earth and another star, it is called an "occultation", from the Latin word "occult" or "hidden". The light measurement from the star will be slightly decreased when a planet passes in front of the star. Think of it as a very par away eclipse. This only works for very large planets. 2. Gravitational "wobble": A large planet attracts a star as much as the star attracts the planet, and they both orbit their joint center of gravity. Because the star is so much more massive than the planet, the star only wobbles very slightly, but over long periods it is possible to notice the differences.
