Pada 30/06/1908, satu asteroid telah terlepas masuk ke dalam atmosphere bumi dan lebih kurang 24km diatas ruang angkasa sebuah sungai iaitu Sungai Podkamennaya Tunguska di Siberia, telah meletup dengan kuasa letupan 550kiloton. Asteroid ini adalah selebar 17meter (mungkin 20meter) dan kejadian ini digelar Tunguska Event.

Sungguh bernasib baik bahawa Tunguska Event, yang merupakan letupan terbesar pernah terjadi dialam recorded history manusia ini (letupan2 lain hanyalah cerita2 lama dan teori2 tanpa bukti atau penulisan), terjadi di kawasan yang sangat remote dan merupakan antara tempat paling sedikit kepadatan penduduknya didunia (dihari ini, kawasan2 itu mempunyai 1-3 penduduk per kilometer persegi pada banci Jan 2019).

Penyelidik pertama yang berjaya sampai disitu adalah Leonid Kulik (lihat thread Leonid Kulik) pada tahun 1927, dan dari research expedition team diketuai Kulik inilah kita hari ini dapat written dan recorded hsitory, video dan gambar2 dari kejadian itu dan bila expedisi beliau sampai, masih ada 700 penduduk asal yang menyaksikan kejadian ini dan keterangan mereka diambil oleh nya.

Kulik dan teamnya sangat terkejut bila sampai disitu, kerana 80juta pokok didapati tumbang, dan mereka tumbang dari akarnya (bukan patah batang pokok etc) dan tumbang dalam 2150km persegi. Kulik pergi 3 kali ke tempat yg sangat sukar itu iaitu 2 kali lagi pada tahun 1929 dan 1938 namun beliau tidak dapat merumuskan dengan tepat apakah penyebabnya, tetapi tekaan beliau agak dekat. Kini, kita ketahui ianya adalah Asteroid.

Setiap tahun, pada 30 August, dunia celebrate hari ini untuk mengenang Tunguska Event dengan menamainya The Asteroid Day.

meteor tu kejadian kepada benda dari angkasalepas ke udara bumi, kan?? eg apa2 yg dapat masuk kedalam atmosphere bumi (dan terbakarlah sebab bergesel dgn molecule udara), maka pembakaran dia tu dipanggil meteor; apa2 pun lah eg meteoroids, asteroids, comets. asteroids ni celestial body yg rocky, besar tapi tk mcm planets lah sizenya; meteoroids ni yg halus2. comet tu ice kan?

eh, ye tak ya juga cik seri.
ye lah, kerana beberapa lama juga, maybe decades, ramai scientists thought bahawa yang masuk ke ruang udara Tunguska itu adalah comet kecil.
only bila byk research into large explosions, into celestial bodies punya orbits, that mereka mula ragu2 that it was a comet

ya, walaupun hanya a movie, tetapi ada beberapa theory yang space scientists sudah dapat tahu tentang asteroids (depa ni rocky, tak aktif, hanya orbiting the sun beramai2 dgn asteroids2 lain). berkaitan dgn hubungan asteroids dan atmosphere bumi, ialah:
1) setiap tahun, on overage 1 asteroid sebesar kereta akan terlepas dan masuk ke orbit2 planet lain dan akan termasuk ke orbit bumi dan 1 darinya every year akan tepat2 nya msuk orbit kita semasa bumi tgh lalu di point tersebut.. ia akan berada dalam collison course dgn bumi lah, dan ia akan serta merta terbakar kerana friction dan kelajuan nya yg terlampau tu, lalu akan jadi bola api yg besar dan impressive..

2) yg lebih menakutkan, setiap 2000 tahun, 1 asteroid sebesar padang akan masuk macam 1) tu dan akan merosakkan area yg really besar

Tunguska ini sizenya tak la sebesar no 2), jadi, frequency ia utk berlaku adalah lebih tinggi ie bukanlah sekali dlm 2000 tahun
