Life?

Halleys comet has no possible way of having life on it, because it is not a planet it is infact a comet and has an obits too fast. halleys comet can not have life becasue it does not fit theese chariteristics needed to have life:
1. it does not have any liquid water
2. it does not have any magnedic field
3. it does not have any oxigin atmostsphere
So because Halleys comet does not fit any of theese charteristics I belive this body does not carry life. So you can get rid of the thought of any alians living on this comet:


although There is a chance that there could be life in another part of the solar system. even though its understandble to be very sceptical eneladus could in fact hold life. the body is located in this very solar system (our solar system). scintiest belive that it could have life on it becasuse of the differaent terain it has on it "Unlike Mimas, Enceladus displays at least five different types of terrain. Parts of Enceladus shows craters no larger than 35 km in diameter. Other areas show regions with no craters indicating major resurfacing events in the geologically recent past. There are fissures, plains, corrugated terrain and other crustal deformations. All of this indicates that the interior of the moon may be liquid today, even though it should have frozen aeons ago." says solarviews.com. So it could infact have liquid water on it. I am very sceptical about the planet but i do belive that there is a small chance that it could infact have life on it.

Distance

distance is mesured in 3 differant units kilometers, astronomical units, and light years. kilometers are used mostly to mesure smaller things like the diamiter of bodies. astronomical units (AU) are useually used to find the distance between two planets. light years are mostly to find out biger ranges for an example how long it takes to get from one galixy to another. The basic ratio of light years are 1 light year is equal to 9,460,730,472,580.8 kilometers or sumed up in signtific notation; 9.4605284 × 1015 kilometers

halleys comet as of now is 4,740,000,000 km away from hearth and that would take about 20 years to reach halleys comet from where it is now. Although i don,t think humans would get there because at the rate a comet is moving its distance always will change. So i don't think that humans will ever be able to land non the less go to halleys comet, but we are able to see it from earth every few years.

A bit more about Edmond halley

Sir Edmond Halley, a discoverer. Born 1656, he found out in 1705 that a comet was periodic and would make another appearance in 1758. As predicted the comet appeared and then was known as Comet Halley. In 1742 Halley died and never really got to see his prediction come true. Thus not letting him live in the glory of his prediction was right.
in 1716 Haley also suggested that there were two types of diving bells that would enable people to explore the deep sea. Halley investigated different theories and understanding winds and tied He also suggested that the earth is made of concentric spheresthe size of the inner planets each of which might contain life , which as we know today is not true.

Halleys comet formation

the way that halley's comet starts to form begains with a nebul; this is where gas and dust begain to collect. Once the gas and particalls collect they begain to freez in the cold outer solar system, where the object begains to acculrate ( smaller objects begain to fuse to create a bigger whole object.) The comet soon begain to orbit around the sun at a very fast spead that created a tail, of gas and dust left behind.

Planet?

Pluto; a dwarf planet because it does not meet the expectations of a regular planet in our solar system. Over the last few decades sintest have come to the conclustion that pluto is in fact a dwarf planet. The reason that brought them to this conclustion is the fact that pluto does not have a strong enough gravitational pull to clear the neighborhood of its orbit. although it does meet most of the expections of a planet it does not have enough mass for a strong enough gravitaional pull. To be a planet a body needs to meet 3 main expections;

1. it needs to be in orbit around the sun

2. it needs to have enough gravity to pull itself into a spherical shape

3. it needs to have "cleared the neighborhood" of its orbit

halleys comet fun facts

A second after the big bang, the universe looked like comic clusters forming in space and universe. The universe was much differant from today because now there are differant planets and stars (Comets.) most comets are brown compressed rock shooting through space. kind of like haley comet.
