През 2003 г. е открит и 2003 UB313, транснептунов обект, по-голям от Плутон. </p><p>Споровете на Общото събрание на IAU се водят за приемането на един от двата строги критерия – т. нар. „физическо“ определение: тяло, което под действието на гравитационните сили е придобило кръгла форма (т.е. към този момент Слънчевата система би имала 12 планети), или „динамичното“ определение: тяло, което е разчистило своята <a href="/wiki/%D0%9E%D1%80%D0%B1%D0%B8%D1%82%D0%B0" title="Орбита">орбита</a> от междупланетни отломки, има малък ексцентрицитет, не пресича орбитата на друга планета и има малък наклон към еклиптиката (т.е. планетите са 8). </p><p>Решението, взето от Общото събрание на IAU, е компромисно решение, което разграничава три типа тела в Слънчевата система: терминът „малки планети“ отпада и се заменя с „<a href="/wiki/%D0%9F%D0%BB%D0%B0%D0%BD%D0%B5%D1%82%D0%B0_%D0%B4%D0%B6%D1%83%D0%B4%D0%B6%D0%B5" title="Планета джудже">планети джуджета</a>“ (като Плутон, Церера, Ерида, Макемаке и др.), и обозначава сферичните тела от Слънчевата система, а терминът „малки тела в Слънчевата система“ обозначава останалите тела, включително и кометите. Спътниците на планетите не са засегнати от това определение. С това си решение отнема статусът на планета на Плутон, обявена за <a href="/wiki/%D0%9F%D0%BB%D0%B0%D0%BD%D0%B5%D1%82%D0%B0_%D0%B4%D0%B6%D1%83%D0%B4%D0%B6%D0%B5" title="Планета джудже">планета джудже</a>. </p><p>Общото събрание на МАС реши планетите и другите тела в Слънчевата система да се класифицират по следния начин: </p> <ol><li>„<a href="/wiki/%D0%9F%D0%BB%D0%B0%D0%BD%D0%B5%D1%82%D0%B0" title="Планета">Планета</a>“ е небесно тяло, което (a) е в орбита около Слънцето, (b) има достатъчно маса, така че собствената му гравитация да преодолява вътрешните сили, действащи при твърдите тела, така че то да се установи в хидростатично равновесие (да е с приблизително кръгла форма), и (c) да е разчистило близките околности на своята орбита.</li> <li>„<a href="/wiki/%D0%9F%D0%BB%D0%B0%D0%BD%D0%B5%D1%82%D0%B0_%D0%B4%D0%B6%D1%83%D0%B4%D0%B6%D0%B5" title="Планета джудже">Планета джудже</a>“ е небесно тяло, което (a) е в орбита около Слънцето (b) има достатъчно маса, така че собствената му <a href="/wiki/%D0%93%D1%80%D0%B0%D0%B2%D0%B8%D1%82%D0%B0%D1%86%D0%B8%D1%8F" title="Гравитация">гравитация</a> да преодолява вътрешните сили, действащи при твърдите тела, така че то да се установи в хидростатично равновесие (да е с приблизително кръгла форма), (c) да не е разчистило близките околности на своята орбита, и (d) да не е спътник.</li></ol> <div class="mw-heading mw-heading2"><h2 id="Международната_година_на_астрономията_2009_(IYA_2009)"><span id=".D0.9C.D0.B5.D0.B6.D0.B4.D1.83.D0.BD.D0.B0.D1.80.D0.BE.D0.B4.D0.BD.D0.B0.D1.82.D0.B0_.D0.B3.D0.BE.D0.B4.D0.B8.D0.BD.D0.B0_.D0.BD.D0.B0_.D0.B0.D1.81.D1.82.D1.80.D0.BE.D0.BD.D0.BE.D0.BC.D0.B8.D1.8F.D1.82.D0.B0_2009_.28IYA_2009.29"></span>Международната година на астрономията 2009 (IYA 2009)</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=%D0%9C%D0%B5%D0%B6%D0%B4%D1%83%D0%BD%D0%B0%D1%80%D0%BE%D0%B4%D0%B5%D0%BD_%D0%B0%D1%81%D1%82%D1%80%D0%BE%D0%BD%D0%BE%D0%BC%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8_%D1%81%D1%8A%D1%8E%D0%B7&amp;veaction=edit&amp;section=4" title="Редактиране на раздел: Международната година на астрономията 2009 (IYA 2009)" class="mw-editsection-visualeditor"><span>редактиране</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=%D0%9C%D0%B5%D0%B6%D0%B4%D1%83%D0%BD%D0%B0%D1%80%D0%BE%D0%B4%D0%B5%D0%BD_%D0%B0%D1%81%D1%82%D1%80%D0%BE%D0%BD%D0%BE%D0%BC%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B8_%D1%81%D1%8A%D1%8E%D0%B7&amp;action=edit&amp;section=4" title="Edit section&#039;s source code: Международната година на астрономията 2009 (IYA 2009)"><span>редактиране на кода</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>По инициатива на Международния астрономически съюз и <a href="/wiki/%D0%AE%D0%9D%D0%95%D0%A1%D0%9A%D0%9E" title="ЮНЕСКО">ЮНЕСКО</a> 2009 година е обявена официално от <a href="/wiki/%D0%9E%D0%B1%D1%89%D0%BE_%D1%81%D1%8A%D0%B1%D1%80%D0%B0%D0%BD%D0%B8%D0%B5_%D0%BD%D0%B0_%D0%9E%D0%9E%D0%9D" title="Общо събрание на ООН">Генералната асамблея на ООН</a> за Международна година на астрономията.

Сега телескопи на земята и в космоса изучават Вселената по 24 часа на ден, отвъд всички дължини на вълната на светлината. Международната година на астрономията 2009 цели да стимулира световния интерес към науките като цяло и към астрономията в частност, особено сред младите хора чрез общата тема „Вселената е Ваша, за да я откриете“.
