话题一颗小行星正在远离地球PassagelAn asteroidthat movedcloser to Earths orbit in recentmonths isnowmoving awayfrom ourplanet asgravity pullsit backtoward thesun.This smallasteroid,about10meters long,was named2024PT

5.

1.It wasrecently pulledcloserto ourplanet by Earths gravitational forces,which led to someinterestingobservations.Scientists sometimescall such objects mini-moons due to theirbehaviorwhen captured by gravity.

2.The Americanspace agencyNASA has itsown viewon this asteroid.It doesntconsider2024PT5a mini-moon asit wasneverfully capturedby Earths gravity.However,NASA doesthink itsaninteresting objectworthy ofstudy.

3.Identifying andtracking suchasteroids is an importanttask forscientists.The asteroidwas first observed onAugust7by twoastronomer brothers fromSpains ComplutenseUniversity of Madrid.They useda telescope in SouthAfricafor the identification.

4.The path of2024PT5is quiteunique.It beganmovingtoward Earthin lateSeptember,with apath similar to ahorseshoe.By January,when itreturns,it willbe moving at morethan doublethe speedfromSeptember.

5.NASA andits internationalpartners areconstantly onthelookout for near-Earth objects.This includesasteroids andcomets within50million kilometersof Earthsorbit.The searchsystem ATLAS,with fourtelescopesin differentlocations,is designedto searchthe wholesky severaltimes eachnight.A.But itsnot alwayseasy tospot thesesmall anddim objects.B.The objectsmovement has been closely monitored byscientists.C.Its movementwas firstdetected bySpanish astronomers.D.Such asteroidsare considerednear-Earth objects.E.It was an objectthat cameunder thespotlight of the scientificcommunity.F.The agencyhas itsown reasonsfor classifyingitina certainway.G.The searchfornear-Earth objectsisacrucial partof spaceresearch.答案

5.GPassage2An asteroid,2024PT5,has beenmaking itsway aroundour solarsystem inan interesting manner.

1.This smallasteroid,measuring about10meters long,has astory worthexploring.It waspulled closertoEarthby ourplanetsgravitational forcesrecently,sparking scientificinterest.

2.The conceptof mini-moons isrelevant here.Scientists sometimeslabel suchobjectsas mini-moons becauseof theirbehaviorwhen influencedbyEarths gravity.However,NASA has a differenttake on2024PT

5.

3.NASAs stanceon2024PT5is quitedistinct.It doesntconsider thisasteroid atrue mini-moon asitwasnt fullycapturedbyEarthsgravity.Nevertheless,they recognizeits valuefor study.

4.The discoveryof2024PT5isaninteresting tale.Two astronomerbrothers fromSpains ComplutenseUniversityof Madridfirstobservedit onAugust7,using atelescopeinSouthAfrica.

5.The futurepathof2024PT5is alsobeing closelywatched.Its expectedtoreturn to Earths vicinity in January,movingata muchhigher speedthan before.And scientistspredict its next closeapproach toEarth willbe in

2055.A.The pathof the asteroid isa keyaspect ofits study.B.The smallsize oftheasteroiddoesnt makeit anyless important.C.These objectsact likea temporarymoon whenunder Earthsinfluence.D.Their observationsledtotheidentificationof thisunique asteroid.E.The agencyhas itsown criteriafor classifyingspace objects.F.Its normalfor asteroidsto beaffected bygravitationalforces.G.This asteroidsmovement patternis attractingscientific attention.答案

5.APassagesThe asteroid2024PT5hasbeenan objectof greatinterest inthe scientificworld.

1.Firstly,its sizeand initialapproach toEarth areremarkable.Measuringabout10meters long,it wasdrawn closerto ourplanet byEarths gravitationalpullin recentmonths.

2.The termmini-moon comesinto playwhen discussing2024PT

5.Scientists oftenuse thisterm forsuchobjectsduetotheir moon-likebehavior whenunder Earthsgravity.But NASAhasadifferent perspective.

3.NASAs viewon2024PT5is basedonspecific criteria.It doesntclassify2024PT5asamini-moon asit wasntfullycaptured byEarthsgravity.Instead,they seeit asaninterestingobject forresearch.

4.The discoveryprocessof2024PT5is alsofascinating.Two astronomerbrothersfromSpainsComplutense UniversityofMadridfirst spottedit onAugust7,using atelescopein SouthAfrica.

5.Looking ahead,the futuremovement of2024PT5is beingcloselymonitored.Itwill returntoEarthsvicinityinJanuary,and thenmove furtherinto thesolarsystem whileorbiting thesun.Scientists arealso predictingitsnextcloseapproach in

2055.A.Their discoverywas thestarting pointof in-depth researchon thisasteroid.B.This behaviormakes themsimilartothe moonin someaspects.C.The sizeoftheasteroid mightbe small,but itssignificance islarge.D.The agencyhasitsown wayof categorizingspace entities.E.The asteroidsmovement isa complexyet interestingsubject.F.This initialapproach ledto aseries ofscientific investigations.G.Scientists arealways eagerto studynew andunique spaceobjects.答案
