Find the odd man out in the following rocket star planet comet

Objects of interstellar origin in our own Solar System continue to draw attention. Centaurs, most of which do not occupy such extreme positions, are a population of asteroids moving between the outer planets in what have until now been considered unstable orbits. In those days, the Sun would have been part of a star cluster, with many young stars in close proximity. The authors believe they can identify 19 asteroids that once orbited other stars and now orbit the Sun. The new study extends their simulations to the past orbits of 17 high-inclination Centaurs and two trans-Neptunian objects KV42 and KT19 with polar orbits.

A New Mini-Moon Was Found Orbiting Earth. There Will Be More.

The bizarrechemical make-up of a comet suggests the blob of ice is an interloper, possiblyflung into our solar system from beyond, astronomers now say, adding that thewacky comet is forcing them to create a new category for such objects. Since then, the icy denizen has made a few appearances, including onein Theoddball, described in the November issue of the Astronomical Journal ,could shed light on the formation and evolutionof comets.

These blobs of dustand frozen gases may be the oldest, most primitive bodies in the solarsystem. In fact, they hold the earliest record of material from the nebulathat formed the sun and planets.

Schleichermeasured the amounts of certain carbon and other compounds in the coma or head of Machholz1 in He compared the composition with information from other comets,finding that Machholz 1 had an odd make-up. Particularly, the comet containsmuch less of a carbon-nitrogen molecule called cyanogen, by a factor of about72, compared with the average found in other comets.

The comet also containedmuch less of two molecules called C2 and C3 which have two and three atoms ofcarbon in their structures, respectively than the average comet. Schleicher puts forth three scenarios that could be responsible for theodd chemistry, although no one explanation stands out as right on.

Onepossible explanation is that Machholz 1 did not originate in the solar system,but instead escaped from another star? In this scenario, the other star'sproto-planetary disk the disk of debris from which planets are thought toform might have had a lower abundance of carbon, resulting in allcarbon-bearing compounds having lower abundances.

Severalcomets previously in our solar system have gotten the boot when their orbitscame into contact with that of Jupiter, whose gravity kicked them out. Anotherpossible explanation for Machholz 1's anomalous composition is that it formed insidethe solar system but even farther from the sun in a colder or more extremeenvironment than othercomets.

A thirdpossibility is that Machholz 1 originated as a so-called carbon-chain depletedcomet, but that this chemistry was subsequently altered by extreme heat and socyanogen was also depleted. While no other comet has exhibited changes inchemistry due to subsequent heating by the sun, Machholz 1's orbit takes thecomet to well inside Mercury's orbit every five years. Other comets get evencloser to the sun, but not as often. However, headded, the only other comet, called Yanaka, to show less cyanogen than istypical never reached such high temperatures.

Thisimplies that [cyanogen] depletion does not require the chemical reactionsassociated with extreme heat," Schleicher said. The resultsplace Machholz 1 into a new class of comets.

Until now, astronomers haveclumped comets into one of two classes based on their chemical compositions. Mostcomets, considered members of the "typical" class, have long residedin the Oort Cloud at the fringes of our solar system but are thought to haveoriginally formed amidst the giant planets, particularly between Saturn, Uranusand Neptune. Other members of this class arrived from the Kuiper Belt, a regionof icy objects beyond Neptune but closer in than the Oort Cloud.

The secondclass includes comets with varying depletions of certain carbon molecules,including the C2 and C3 molecules. Nearly all of these comets calledcarbon-chain depleted comets have orbits that suggest they arrived from theKuiper Belt. For this and other reasons, scientists think the carbon depletionis associated with conditions that existed when the comets formed, perhapswithin an outer, colder region of the Kuiper Belt.

The newclass of comets, which would include Machholz 1 and possibly Yanaka, would becharacterized by low levels of at least three carbon compounds? C2, C3 andcyanogen. And as of now, these comets would be considered of unknown origin, Schleichersaid.

The comet,now bound in an orbit around the sun, is expected to come into view again in, at which time Schleicher expects astronomers will point other instrumentstoward it to measure even more carbon-bearing molecules.

Thirsty? Have a comet!

About 4 a. If the discovery holds up, the object, named CD3 for now, would be the second mini-moon ever found. The solar system is full of primordial crumbs, most of which circle the sun in the asteroid belt between Mars and Jupiter.

Retrograde motion in astronomy is, in general, orbital or rotational motion of an object in the direction opposite the rotation of its primary , that is, the central object right figure. It may also describe other motions such as precession or nutation of an object's rotational axis.

Formation of the Solar System The Solar System Today When we make a list of the characteristics of the solar system as we see it today, we find the following facts: The planet orbits have the following characteristics They all go around the Sun in the same direction right hand rule. The right hand rule is this: point your thumb in the direction of the north pole, and the object rotates or revolves in the direction that your fingers curl. The Sun rotates in this same, right-hand-rule direction. All planetary orbits lie in nearly the same plane. All planetary orbits are nearly circular eccentricity near zero.

Odd Comet Possibly from Another Star System

In every competitive exam, Odd Man Out type questions are very common. In odd man out problems all the items given in the question except one follow a certain pattern or a group. That means out of the all given elements, one will not fall into the group due to some difference in the property. That is the odd element. Hence, it is the odd one. From the above, the second one is the feminine of the first one except the first pair. So the answer will be a. In this type, a group of messed letters consisting 3 letters are kept together.

Nine Planets – Astronomy Question

Need online help with writing an Astronomy research project? This can really be a lot of different answers. However, this is all dependant on whether or not you have a clear view across the universe- which would be really difficult! Also, when you consider the force of a black hole, jumping into a collection of them might not be a very wise idea.

A big comet or asteroid crashed into Earth about 65 million years ago. Scientists think this impact may be why the dinosaurs all died. But much earlier in Earth's history, times were worse. Earth had one bad day after another getting hammered by comets, asteroids, and even bigger chunks of rock. Could these space invaders have brought more than death to dinosaurs?

New comet is our second interstellar visitor

Toggle navigation. You can change your option as many times as you like. Find the odd one out from the given alternatives. All others are forms of investments. Answer c. Mizoram, Sikkim and Manipur are states while Kohima is a city. Answer a. Bacteria, germs and microbes are general terms while amoeba is more specific.

Due to complicated gravitational interactions from planets and other bodies, it's expected that our Solar System has ejected various small bodies like comets and asteroids. Since exosolar systems are likely to do the same, it's thought that the vast distances of interstellar space are sparsely populated by these small bodies. As such, we should expect one of these objects to wander through our Solar System, an expectation that was confirmed in with the arrival of 'Oumuamua , an odd, cigar-shaped object that shot through the Solar System at an extreme angle.
