Astronomers Are Tracking Four Potential Interstellar Objects Now In Our Outer Solar System

Using detailed computer models of asteroidal-type objects between the Sun and Jupiter, two Harvard University researchers find that at least four known objects are likely to have origins from outside our solar system.

“The Sun-Jupiter system acts as a fishing net that collects interstellar objects,” Harvard University astrophysicist Abraham Loeb told me. “ At any given time, there are a few thousand trapped objects within the solar system

Our paper, says Loeb, shows that by focusing on objects at high inclinations to the plane of the solar system and on counter-rotating orbits to the planets, we can isolate interstellar objects.

As for the four that the authors have thus far identified as potential interstellar objects?

“ We do not know if they are comets, asteroids, or artifacts ,” Amir Siraj, a Harvard University undergraduate in astrophysics, told me. Until these objects pass close to earth again, he says we won't be able to know. Siraj notes that of the four, object 2018 TL6 will make a close Earth approach in another twenty years.

And as for Oumuamua which NASA classifies as a highly-elongated, rocky, cigar-shaped object with a somewhat reddish hue?

NASA’s Spitzer infrared telescope data rules out typical cometary activity, says Loeb. And he says it also sets an upper limit on Oumuamua's size, which in turn implies a shiny surface, which is at least ten times more reflective than a typical asteroid.

"These results are at odds with the properties of comets and asteroids in the solar system are fully consistent with an artificial origin,” said Loeb.

The name Tycho Magnetic Anomaly-1 (also known as the TMA-1) refers to the strong magnetic field found somewhere in the lunar Crater Tycho by an American scientific satellite. Astronauts find that this magnetic anomaly is caused by an alien Monolith buried about 15 meters below the surface. In the novel, when the Monolith is excavated and examined, it is found to be a black cuboid whose sides extend in the precise ratio of 1 : 4 : 9 (1² : 2² : 3²). In the novel, Clarke suggests that this sequence or ratio extends past the three known spatial dimensions into much higher dimensions.

Why a new discovery in outer space means humans should keep an ‘open mind’ about extraterrestrial life

In October 2017, an elongated interstellar object named “Oumuamua” — the first to enter the solar system — was detected by a survey telescope in Hawaii. A new study published this week in the Astronomical Journal, coauthored by scientists at NASA’s Jet Propulsion Laboratory, uncovered new information that suggested there was a limit to how big Oumuamua actually is, and gave astronomers a better indication of its size.

“I personally think the odds are much better that is something natural, but I don’t want to dismiss the possibility that it could be from an alien civilization. But we have to have an open mind,” Michael Wall, a writer at Space.com and a biologist, told CNBC recently. Scientists believe Oumuamua is shaped like a cigar, approximately 400 feet long and 40 feet wide. However, they are only able to guess based off its changing brightness as it spins. But scientists’ biggest unanswered question is the object’s thickness.

---

Seth Shostak, a SETI research fellow, told CNBC that for that to be true, Oumuamua would have to be about a millimeter thick—about as thick as 5-10 sheets of paper stacked together. According to Wall, scientists originally hypothesized that Oumuamua was a comet or an asteroid. However, both theories were ruled out: Unlike comets studied here on earth, this object does not have a tail, nor jets of gas that a comet would normally emit. If Oumuamua is not a comet or an asteroid, chances of it being a light sail increase. According to SETI’s Cuk, it is possible that outside our solar system, composition of space objects are different. “Maybe in other solar systems comets could be made differently,” Cuk said. That suggests the object could be naturally occurring, despite the fact that nothing like it has ever been seen anywhere near earth before.

NASA learns more about interstellar visitor 'Oumuamua

Date: November 15, 2018
Source: NASA/Jet Propulsion

Laboratory Summary: The first known interstellar object to visit our solar system -- named 'Oumuamua -- was detected in October 2017 by Hawaii's Pan-STARRS 1 telescope. But it was too faint for NASA's Spitzer Space Telescope to detect when it looked more than two months after the object's closest approach to Earth in early September. That 'non-detection' puts a new limit on how large the strange object can be, astronomers now report

---

quote:

---

The new size limit is consistent with the findings of a research paper published earlier this year, which suggested that outgassing was responsible for the slight changes in 'Oumuamua's speed and direction as it was tracked last year: The authors of that paper conclude the expelled gas acted like a small thruster gently pushing the object. That determination was dependent on 'Oumuamua being relatively smaller than typical solar system comets. (The conclusion that 'Oumuamua experienced outgassing suggested that it was composed of frozen gases, similar to a comet.)

---

quote:

---

Subsequent detailed observations conducted by multiple ground-based telescopes and NASA's Hubble Space Telescope detected the sunlight reflected off 'Oumuamua's surface. Large variations in the object's brightness suggested that 'Oumuamua is highly elongated and probably less than half a mile (2,600 feet, or 800 meters) in its longest dimension.

But Spitzer tracks asteroids and comets using the infrared energy, or heat, that they radiate, which can provide more specific information about an object's size than optical observations of reflected sunlight alone would. The fact that 'Oumuamua was too faint for Spitzer to detect sets a limit on the object's total surface area. However, since the non-detection can't be used to infer shape, the size limits are presented as what 'Oumuamua's diameter would be if it were spherical. Using three separate models that make slightly different assumptions about the object's composition, Spitzer's non-detection limited 'Oumuamua's "spherical diameter" to 1,440 feet (440 meters), 460 feet (140 meters) or perhaps as little as 320 feet (100 meters). The wide range of results stems from the assumptions about 'Oumuamua's composition, which influences how visible (or faint) it would appear to Spitzer were it a particular size.
