vesta is the fourth asteroid to be discovered by mankind(1807).it is the third largest asteroid known to mankind(about 500 Km across) .it is located in the main belt of the asteroid belt.it is irregular in shape.it takes 3.632 years to orbit the sun with an average distance of about 353 million km.
Halley's comet is visible every 76 to 79 years. the last appearance was during the 1980's
The five planets visible from Earth without a telescope are Mercury, Venus, Mars, Jupiter, and Saturn. These planets are often visible to the naked eye and can be seen in the night sky from various locations on Earth at different times throughout the year.
Halley's comet is not predicted to hit Earth in the foreseeable future. The next time it will be visible from Earth is in 2061.
No comets are not visble on earth, every 76 years, only Halley's comet is only visible every 76 years
At the end of December 2011, the following comets are all brighter than magnitude 12 as seen from Earth: -- C/2009 P1 Garradd -- P/2011 Y1 Levy -- C/2011 W3 Lovejoy -- 21P Giacobini-Zinner
Next appear in mid-2061
They can be visible from Earth without the aid of a telescope.
Yes, Earth can be seen at night without a telescope. It is visible from space station and other spacecraft. However, it is not visible to the naked eye from the surface of the Earth at night.
because the comet is so far away theat you cant see it without a telescope
Saturn is the outer planet that can be seen from Earth without the aid of a telescope. Its bright rings make it easily visible in the night sky.
Jupiter is the outer planet that can be seen from Earth without the aid of a telescope. It is the fourth brightest object in the sky and is visible to the naked eye.
No. A comet is not usually very big (20km or so). What gives a comet its brightness is its tail, which is seen when it approaches the sun, and the Earth's orbit. Then the heat from the sun leads to the release of vapor and water from the comet (which is basically a dirty snowball) - basically a vast cloud behind it which can be many thousands of kilometres long, which is what we see. At Saturn's orbit, the comet would simply be a dirty snowball, hard to detect even with a powerful telescope. At the low temperatures (like -180c) it wouldn't be releasing any water vapour; at the same time, it would be very far away (at least 1.3 billion km) and it would not be getting much light shone on it (1/90th as much as when it reaches Earth orbit).
Not without a telescope and detailed knowledge of where to look. They're tiny and not close to Earth.
The next comet will be Comet Ison which will pass by the earth in 2013. It will be visible with lenses during late summer and will be visible to the naked eye by approximately November.
Halley's comet is visible every 76 to 79 years. the last appearance was during the 1980's
No, it was last seen from Earth in 1986, 10 years before that, though it was observed in 2003 by what is known as the Very Large Telescope, which is a set of telescopes with great power, that are in Chile.
The next notable comet scheduled to pass by Earth is Comet Leonard, which is expected to be visible in December 2021. It will be the brightest comet of the year and should be observable with binoculars or a small telescope from dark sky locations. Keep an eye out for updates from astronomers as the date approaches for the best viewing opportunities.
