In 2017 , a totally freakish object zip through thesolar system . Nicknamed ' Oumuamua , this interstellar traveler was too far away and too rapid to be identified . Years later , scientists are still puzzling over what it might have been .
It ’s not too tardy to go see , according to a newfangled enquiry paper mail to the preprint websitearXiv . By executing a complex maneuver around Jupiter , a space vehicle launch by 2028 could catch up with ' Oumuamua in 26 long time .
The interloper ‘Oumuamua continues to puzzle astronomers and astrophysicists. Is it really a cigar-shaped rock as this artist’s impression shows?
" What we need is a photograph of it , very close , an in situ photograph , " said lead source Adam Hibberd , a software package engineer at the non-profit-making Initiative for Interstellar Studies ( i4is ) in the United Kingdom . " And the only style we can do that is by sending a charge . "

' Oumuamua was last learn zipping through the solar organisation at 57,000 miles per hour ( 92,000 km / h ) . That velocity — and the target ’s acceleration around the sun — signal that it came from outsidethe solar system . Theories for what it might have been proliferate . A chunk of nitrogen shabu thatsnapped off of an " alien Pluto " ? Aclump of junk from a comet ? A small-arm ofalien technology ?
' Oumuamua ’s passage also remind a ado of melodic theme for how to station a probe to see the object firsthand . ' Oumuamua sped past Saturn ’s orbit in January 2019 and is estimated to be somewhere outside Neptune ’s orbit as of this year , headed toward the constellation Pegasus . Some of the theme on how to chase ' Oumuamua down involved slingshotting a spacecraft around the Lord’s Day , thus enabling a burst of speed without using much fuel . But such a solar maneuver would require heavy solar shielding , which would add weight and expense , Hibberd told Live Science .
Under i4is ' " Project Lyra , '’ Hibberd and his confrere in the U.S. and Europe cooked up an choice , known as a " Jupiter Oberth maneuver . " A spacecraft would launch fromEarth , and then sweep around both Venus and Earth . This would get it to Jupiter with minimal fuel , Hibberd said . Once at Jupiter , the ballistic capsule would burn fuel to speed up , allowing it to slingshot retiring Jupiter toward ' Oumuamua at about 82,800 miles per hour ( 133,200 klick / h ) . Jupiter would n’t give as much of a gravitational help as the sun , Hibberd said , but it could still get the job done .

" Jupiter has one - one-thousandth the mass of the Lord’s Day — so it ’s much less massive — and you do n’t get quite as much , to use the expression , ' bang for your buck , ' but you do get there at pretty high stop number , " he say .
Whether any such mission will ever happen is an undecided motion . Hibberd and his colleagues bow a white paper toNASA’sDecadal Survey , which queries the space community every 10 years for missionary station melodic theme and antecedence .
" We ’ll see what comes of that lily-white paper , " Hibberd said . " We ’re seek to get boost from the scientific community — after all , it would solve a lot of their questions . "
