Unlikely. There are no periodic comets known that will revisit the inner solar system in 2061. And that's 52 years from now; it's impossible to know when a new comet will appear.
So the chance is vanishingly small that a comet will strike the Earth in 2061.
On the other hand, comets or comet-like asteroids have struck the Earth before, so the possibility exists. But hopefully by then, we'll have the technology to detect such a comet far enough from Earth and be able to deflect it - or capture it. It would be nice to have a second Moon.
Comets were considered to be bad omens until the sixteenth century. They were usually thought to predict the downfalls of kings or kingdoms. There isn't a documented case of a comet being visible to anyone in the Philippines, but they most likely believed this superstition, until philosophers and scientists began to study them.
A comet with an elliptical orbit will periodically come close to the sun at its closest point (perihelion) and then move away to its farthest point (aphelion). So, a comet with an elliptical orbit would indeed come near the sun again after moving away. The exact timing of when it would be close to the sun again depends on the specifics of its orbit.
Comets do not typically accrete (add material) in their orbits. Comets were formed along with the solar system billions of years ago. They are gradually vaporized as they circle the Sun, either becoming small asteroids, breaking up completely, or impacting planets such as Jupiter.
It starts to be visible in the northern hemisphere's autumn, but it isn't really properly visible until winter arrives. It is then visible throughout the winter before disappearing in early spring.
The red giant star Betelgeuse is the bright reddish star at the "shoulder" of Orion, the Hunter. Orion is one of the most distinctive constellations in the winter sky, and is easily visible in the winter and early spring. In this season, Orion is setting as the Sun goes down, and it will not be especially visible until the late fall again, when it will rise at sunset.
Halley's Comet was last seen in 1986 and won't be visible again until 2061.
To VERY powerful telescopes, yes. It won't be back in the inner system and visible to the naked eye again until around 2061.
Halley's comet will next be visible from Earth in 2061, approximately every 76 years. Hale-Bopp, on the other hand, has an orbital period of about 2,532 years, so it won't be visible again from Earth until around the year 4385.
That was Halley's Comet - it will not be seen again until 2062
Halley's comet last passed through the inner solar system ... becoming bright enough to be visible ... in the mid 1980s. It's not expected to be visible again, even with significant optical enhancement, until some short time before 2060.
Every 75-76 years. It last appeared in view on February 9th 1986 and will not be visible again until July 28th 2061
A comet emits no light of its own, until close enough to be illuminated and stimulated by radiation from the sun.
Halley's Comet is moving away (in 2010 - when this answer was written), it came close in 1986, it will continue to move away until about 2030 then re-approach and become visible again in mid 2061.
No. It will be not be seen from Earth again until the year 2061.
Comet Hale-Bopp is still visible in very large telescopes; estimates indicate that it will be visible until 2030, and may be visible longer than that in the improved telescopes of ten years from now.Comet Hale-Bopp is not expected to return to the inner solar system until the year 4390.
it was last seen in 1986 and wont be able to be seen again until 2061.
Difficult to know. The comet which later came to bear Edmund Halley's name has probably been visible throughout human history. But not until Halley did most people accept that all those different comets were all different visits of the SAME comet
