Loki. In Avengers: Infinity War, Thor said he was 1500 years old (ref: https://movieweb.com/thor-age-avengers-infinity-war/). If Loki isn't even 1100, then Thor is definitely physically older.
Confirmed dates: Loki's birth. Which is on 965 A.D. In Thor, Loki and Thor look about the same age. In Ragnarok, Thor confirms they were about the same age (8) when Loki stabbed him.
In Thor: The Dark World, Odin reminds Loki that Asgardians are not immortal and have lifespans as humans do, to which Loki responds: "Give or take 5,000 years." From this, it can be calculated that Asgardians live to about 5,100, with Loki being around 1050 years old in the MCU.
In the original mythology, Loki is a blood-brother to Odin, making him an adopted uncle to Thor. (He's also father to Hela and the Midgard Serpent and the Fenris Wolf, mother to Odin's horse…)

Did Loki love Thor as a brother?
On Sakaar, Thor decided that because of their differences and distinct objectives in life, the best would be if they parted ways with each other. This hurts Loki who, despite everything, also deeply loves his brother.
Loki often hid a degree of jealousy that Thor was to become King, and felt that Odin perhaps favoured Thor over him. As Thor was always the center of attention, Loki found himself longing for a spotlight over the years, which manifested itself in extreme attention-seeking behaviour.
Asgardians live for about 5,000 years and Loki's only been around for 1,070 of those years, which, relative to humans, makes him about 21.4 years old. Thor, on the other hand, is 1,500 years old, which makes him about 30 years old in human years.
The villain in Marvel Cinematic Universe (MCU) is the strongest villain that Avengers have ever face. He's the son of Alars, a Titans, which considered as the strongest race, just like gods. But who would have thought if Thanos in MCU is thousand years old! His age even surpasses Thor, the god of thunder himself.
While Steve Rogers gets the title of the oldest human avenger, Thor Odinson, as the mighty Asgardian God of Thunder, has a much longer life span than any of his Earth-born friends.
Loki Laufeyson was the biological son of Laufey, King of the Frost Giants, who was abandoned and left to die shortly after his birth. Found by Odin, Loki was taken to Asgard and raised by him and Frigga as an Asgardian prince, along with Thor, becoming the Asgardian God of Mischief.
While the Loki of the Marvel comics and films does derive his cunning character from the Loki of Norse myth, the biggest difference is that in the Marvel universe, Loki is depicted as the adopted brother and son of Thor and Odin.
Loki is not a direct analogue for Jesus. He is no Aslan of Narnia, but his story may just be a conversation starter for people who still long for transcendent mercy in a world that knows too much of cold materialism, crass manipulation, and naked coercion.
Here, holding on to all of the timelines, he became a kind of tree god, physically representing the Norse tree of life, Yggdrasil. It was a poignant and painful ending for Loki, who now seems to be sentenced to being alone for eternity as he watches over the timelines.
His weapons of choice are throwing knives. Loki is portrayed by Tom Hiddleston in the MCU with a height of 6'2” (1.88 m). The comic book height of Loki is 6'4” (1.93 m). Loki is a fictional prince of Asgard and god of mischief in Thor, The Avengers, and the extended Marvel franchise.
This makes Thor 447 years OLDER than Loki who, we can reasonably assume, was born in 965 (AD) as shown at the beginning of Thor (2011). Thus, in Thor: Ragnorak (2017) Thor would have been 1,499 years old, and Loki would be 1,052 years old.
Marvel Studios Loki is roughly 1,047 years old during the events of The Avengers. In the opening to Thor, we see Odin rescuing the baby Loki in 965 A.D. He would die in the year 2018 during the events of Infinity War, so he would have been 1,053 years old.
Asgardians age as humans do for the first 20-or-so years of their lives. Upon reaching early adulthood, they begin to age much more slowly. Asgardians possess different internal anatomy from humans, with their bones, tissue, and skin denser.
He always hated Balder, and when Balder became virtually unkillable, he found a loophole and tricked Balder's own brother into killing him. And he and Heimdall never got along. They fought constantly over the years, and eventually, kill each other at Ragnarok. Does Loki really hate Thor?
The spell was permanent, making it so Loki only reverted to having blue skin when touching a Frost Giant or one of their artifacts. Since Loki's appearance was a spell, not just an illusion, it could not be broken or reversed by Odin's death.
Most Marvel fans think that Odin favors Thor over Loki because the former is his natural son, while Loki is the adopted son of the giant Laufey. However, there is another, much deeper reason for Odin's favoritism, and it hides in the one-eyed god's past and his relationship with his brother Cul, the God of Fear.
