What bright star can be occulted by a planet?
Three first magnitude stars appear well within that band – Regulus, Spica and Antares – meaning they may be occulted by the Moon or by planets.
What is a occultation in astronomy?
occultation, complete obscuration of the light of an astronomical body, most commonly a star, by another astronomical body, such as a planet or a satellite. Hence, a total solar eclipse is the occultation of the Sun by the Moon.
What is the meaning of a occultation?
Definition of occultation 1 : the state of being hidden from view or lost to notice. 2 : the interruption of the light from a celestial body or of the signals from a spacecraft by the intervention of a celestial body especially : an eclipse of a star or planet by the moon.
What celestial objects can be occulted by the Moon?
Occultations by the Moon Any star with an ecliptic latitude of less than 6.5 degrees can be occulted by the Moon since it has an inclined orbit to the ecliptic. The three first magnitude stars, Spica, Antares, and Regulus, are close to the ecliptic and can be occulted by planets and the Moon.
Which star was hidden behind the Moon in 2016?

What is the difference between an eclipse and occultation?
Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth’s shadow hides the Moon from view. An occultation occurs when a celestial object is eclipsed by the Moon or another solar system body.
How do you pronounce occultation?
Break ‘occultation’ down into sounds: [OK] + [UL] + [TAY] + [SHUHN] – say it out loud and exaggerate the sounds until you can consistently produce them. Record yourself saying ‘occultation’ in full sentences, then watch yourself and listen.
What planet hides behind the Moon?
Venus
Disappearing Act: Venus Hides Behind the Moon Before Dawn on Thursday. When the moon’s in the sky, and Venus goes “goodbye,” that’s an occultation.
What is it called when Mercury passes in front of the Sun?
When Mercury is near the node of its orbit, it passes through the orbital plane of the Earth. If an inferior conjunction occurs as Mercury is passing through its orbital node, the planet can be seen to pass across the disk of the Sun in an event called a transit.
What is occultation and eclipse?
Occultations are regular, predictable events because planets, dwarf planets, moons, and asteroids orbit the Sun and pass in front of stars in the background. Our Moon occults, or eclipses, the Sun four to six times each year. If you are within the path of the Moon’s shadow, you will see a total eclipse.
What is difference between eclipse and occultation?
Can Mercury block the Sun?
But Mercury is much farther from Earth. That’s what makes it look so tiny from Earth. As such, even though Mercury will pass in front of the sun, it won’t be able to block much sunlight. That’s what distinguishes a transit from an eclipse.
Will Mercury fall into the Sun?
So, Mercury is unlikely to fall into the Sun. In about 6 billion years time, the Sun will run out of Hydrogen fuel in its core. At this stage the Sun will expand into a red giant. As the Sun expands it will consume Mercury, Venus and possibly the Earth.
What happens when a star occultes the Moon?
If there were gases enveloping the Moon, an occulted star would shimmer and fade as it approached the lunar disc before finally fading out. A lunar occultation of Venus is quite a sight, since through a telescope you’ll be able to see a phase on both the planet and the Moon.
What is an occultation in astronomy?
An occultation occurs when a solar-system body passes in front of a more distant object (e.g. a star or another solar system body), partially or totally hiding the more distant object and momentarily blocking its light. Each occultation can be seen only at the right time and from a limited part of…
How do you know if an asteroid occulted a star?
In an asteroid occultation, the observer must find the star to be occulted and monitor the star to watch for any drop in brightness that would signal an occultation. Asteroid occultation events typically last several seconds but may observers may record much shorter or much longer events in rare cases.
How do you find a lunar occultation?
Lunar occultations are ideally suited for small telescopes since they do not require locating a faint star in the sky. To observe a total lunar occultation of a star, simply find the Moon and locate the position along the edge of the lunar surface where the star is predicted to be as the moon moves in front of it.
